-3.1 `strtoflt128' -- Convert from string
-========================================
-
-The function `dmath_strtopQ' converts a string into a `__float128'
-number.
-
-Syntax
-     `__float128 strtoflt128 (const char *s, char **sp)'
-
-_Arguments_:
-     S          input string
-     SP         the address of the next character in the string
-
-     The argument SP contains, if not `NULL', the address of the next
-     character following the parts of the string, which have been read.
-
-Example
-          #include <quadmath.h>
-
-          int main ()
-          {
-            __float128 r;
-
-            r = strtoflt128 ("1.2345678", NULL);
-
-            return 0;
-          }
-

-
-3.2 `quadmath_snprintf' -- Convert to string
-============================================
-
-The function `quadmath_snprintf' converts a `__float128' floating-point
-number into a string.  It is a specialized alternative to `snprintf',
-where the format string is restricted to a single conversion specifier
-with `Q' modifier and conversion specifier `e', `E', `f', `F', `g',
-`G', `a' or `A', with no extra characters before or after the
-conversion specifier.  The `%m$' or `*m$' style must not be used in the
-format.
-
-Syntax
-     `int quadmath_snprintf (char *s, size_t size, const char *format,
-     ...)'
-
-_Arguments_:
-     S          output string
-     SIZE       byte size of the string, including tailing NUL
-     FORMAT     conversion specifier string
-
-Example
-          #include <quadmath.h>
-          #include <stdlib.h>
-          #include <stdio.h>
-
-          int main ()
-          {
-            __float128 r;
-            int prec = 20;
-            int width = 46;
-            char buf[128];
-
-            r = 2.0q;
-            r = sqrtq (r);
-            int n = quadmath_snprintf (buf, sizeof buf, "%+-#*.20Qe", width, r);
-            if ((size_t) n < sizeof buf)
-              printf ("%s\n", buf);
-              /* Prints: +1.41421356237309504880e+00 */
-            quadmath_snprintf (buf, sizeof buf, "%Qa", r);
-            if ((size_t) n < sizeof buf)
-              printf ("%s\n", buf);
-              /* Prints: 0x1.6a09e667f3bcc908b2fb1366ea96p+0 */
-            n = quadmath_snprintf (NULL, 0, "%+-#46.*Qe", prec, r);
-            if (n > -1)
-              {
-                char *str = malloc (n + 1);
-                if (str)
-                  {
-                    quadmath_snprintf (str, n + 1, "%+-#46.*Qe", prec, r);
-                    printf ("%s\n", str);
-                    /* Prints: +1.41421356237309504880e+00 */
-                  }
-                free (str);
-              }
-            return 0;
-          }
-
-
-   On some targets when supported by the C library hooks are installed
-for `printf' family of functions, so that `printf ("%Qe", 1.2Q);' etc.
-works too.

-
-     Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
-     `http://fsf.org/'
-
-     Everyone is permitted to copy and distribute verbatim copies
-     of this license document, but changing it is not allowed.
-
-  0. PREAMBLE
-
-     The purpose of this License is to make a manual, textbook, or other
-     functional and useful document "free" in the sense of freedom: to
-     assure everyone the effective freedom to copy and redistribute it,
-     with or without modifying it, either commercially or
-     noncommercially.  Secondarily, this License preserves for the
-     author and publisher a way to get credit for their work, while not
-     being considered responsible for modifications made by others.
-
-     This License is a kind of "copyleft", which means that derivative
-     works of the document must themselves be free in the same sense.
-     It complements the GNU General Public License, which is a copyleft
-     license designed for free software.
-
-     We have designed this License in order to use it for manuals for
-     free software, because free software needs free documentation: a
-     free program should come with manuals providing the same freedoms
-     that the software does.  But this License is not limited to
-     software manuals; it can be used for any textual work, regardless
-     of subject matter or whether it is published as a printed book.
-     We recommend this License principally for works whose purpose is
-     instruction or reference.
-
-  1. APPLICABILITY AND DEFINITIONS
-
-     This License applies to any manual or other work, in any medium,
-     that contains a notice placed by the copyright holder saying it
-     can be distributed under the terms of this License.  Such a notice
-     grants a world-wide, royalty-free license, unlimited in duration,
-     to use that work under the conditions stated herein.  The
-     "Document", below, refers to any such manual or work.  Any member
-     of the public is a licensee, and is addressed as "you".  You
-     accept the license if you copy, modify or distribute the work in a
-     way requiring permission under copyright law.
-
-     A "Modified Version" of the Document means any work containing the
-     Document or a portion of it, either copied verbatim, or with
-     modifications and/or translated into another language.
-
-     A "Secondary Section" is a named appendix or a front-matter section
-     of the Document that deals exclusively with the relationship of the
-     publishers or authors of the Document to the Document's overall
-     subject (or to related matters) and contains nothing that could
-     fall directly within that overall subject.  (Thus, if the Document
-     is in part a textbook of mathematics, a Secondary Section may not
-     explain any mathematics.)  The relationship could be a matter of
-     historical connection with the subject or with related matters, or
-     of legal, commercial, philosophical, ethical or political position
-     regarding them.
-
-     The "Invariant Sections" are certain Secondary Sections whose
-     titles are designated, as being those of Invariant Sections, in
-     the notice that says that the Document is released under this
-     License.  If a section does not fit the above definition of
-     Secondary then it is not allowed to be designated as Invariant.
-     The Document may contain zero Invariant Sections.  If the Document
-     does not identify any Invariant Sections then there are none.
-
-     The "Cover Texts" are certain short passages of text that are
-     listed, as Front-Cover Texts or Back-Cover Texts, in the notice
-     that says that the Document is released under this License.  A
-     Front-Cover Text may be at most 5 words, and a Back-Cover Text may
-     be at most 25 words.
-
-     A "Transparent" copy of the Document means a machine-readable copy,
-     represented in a format whose specification is available to the
-     general public, that is suitable for revising the document
-     straightforwardly with generic text editors or (for images
-     composed of pixels) generic paint programs or (for drawings) some
-     widely available drawing editor, and that is suitable for input to
-     text formatters or for automatic translation to a variety of
-     formats suitable for input to text formatters.  A copy made in an
-     otherwise Transparent file format whose markup, or absence of
-     markup, has been arranged to thwart or discourage subsequent
-     modification by readers is not Transparent.  An image format is
-     not Transparent if used for any substantial amount of text.  A
-     copy that is not "Transparent" is called "Opaque".
-
-     Examples of suitable formats for Transparent copies include plain
-     ASCII without markup, Texinfo input format, LaTeX input format,
-     SGML or XML using a publicly available DTD, and
-     standard-conforming simple HTML, PostScript or PDF designed for
-     human modification.  Examples of transparent image formats include
-     PNG, XCF and JPG.  Opaque formats include proprietary formats that
-     can be read and edited only by proprietary word processors, SGML or
-     XML for which the DTD and/or processing tools are not generally
-     available, and the machine-generated HTML, PostScript or PDF
-     produced by some word processors for output purposes only.
-
-     The "Title Page" means, for a printed book, the title page itself,
-     plus such following pages as are needed to hold, legibly, the
-     material this License requires to appear in the title page.  For
-     works in formats which do not have any title page as such, "Title
-     Page" means the text near the most prominent appearance of the
-     work's title, preceding the beginning of the body of the text.
-
-     The "publisher" means any person or entity that distributes copies
-     of the Document to the public.
-
-     A section "Entitled XYZ" means a named subunit of the Document
-     whose title either is precisely XYZ or contains XYZ in parentheses
-     following text that translates XYZ in another language.  (Here XYZ
-     stands for a specific section name mentioned below, such as
-     "Acknowledgements", "Dedications", "Endorsements", or "History".)
-     To "Preserve the Title" of such a section when you modify the
-     Document means that it remains a section "Entitled XYZ" according
-     to this definition.
-
-     The Document may include Warranty Disclaimers next to the notice
-     which states that this License applies to the Document.  These
-     Warranty Disclaimers are considered to be included by reference in
-     this License, but only as regards disclaiming warranties: any other
-     implication that these Warranty Disclaimers may have is void and
-     has no effect on the meaning of this License.
-
-  2. VERBATIM COPYING
-
-     You may copy and distribute the Document in any medium, either
-     commercially or noncommercially, provided that this License, the
-     copyright notices, and the license notice saying this License
-     applies to the Document are reproduced in all copies, and that you
-     add no other conditions whatsoever to those of this License.  You
-     may not use technical measures to obstruct or control the reading
-     or further copying of the copies you make or distribute.  However,
-     you may accept compensation in exchange for copies.  If you
-     distribute a large enough number of copies you must also follow
-     the conditions in section 3.
-
-     You may also lend copies, under the same conditions stated above,
-     and you may publicly display copies.
-
-  3. COPYING IN QUANTITY
-
-     If you publish printed copies (or copies in media that commonly
-     have printed covers) of the Document, numbering more than 100, and
-     the Document's license notice requires Cover Texts, you must
-     enclose the copies in covers that carry, clearly and legibly, all
-     these Cover Texts: Front-Cover Texts on the front cover, and
-     Back-Cover Texts on the back cover.  Both covers must also clearly
-     and legibly identify you as the publisher of these copies.  The
-     front cover must present the full title with all words of the
-     title equally prominent and visible.  You may add other material
-     on the covers in addition.  Copying with changes limited to the
-     covers, as long as they preserve the title of the Document and
-     satisfy these conditions, can be treated as verbatim copying in
-     other respects.
-
-     If the required texts for either cover are too voluminous to fit
-     legibly, you should put the first ones listed (as many as fit
-     reasonably) on the actual cover, and continue the rest onto
-     adjacent pages.
-
-     If you publish or distribute Opaque copies of the Document
-     numbering more than 100, you must either include a
-     machine-readable Transparent copy along with each Opaque copy, or
-     state in or with each Opaque copy a computer-network location from
-     which the general network-using public has access to download
-     using public-standard network protocols a complete Transparent
-     copy of the Document, free of added material.  If you use the
-     latter option, you must take reasonably prudent steps, when you
-     begin distribution of Opaque copies in quantity, to ensure that
-     this Transparent copy will remain thus accessible at the stated
-     location until at least one year after the last time you
-     distribute an Opaque copy (directly or through your agents or
-     retailers) of that edition to the public.
-
-     It is requested, but not required, that you contact the authors of
-     the Document well before redistributing any large number of
-     copies, to give them a chance to provide you with an updated
-     version of the Document.
-
-  4. MODIFICATIONS
-
-     You may copy and distribute a Modified Version of the Document
-     under the conditions of sections 2 and 3 above, provided that you
-     release the Modified Version under precisely this License, with
-     the Modified Version filling the role of the Document, thus
-     licensing distribution and modification of the Modified Version to
-     whoever possesses a copy of it.  In addition, you must do these
-     things in the Modified Version:
-
-       A. Use in the Title Page (and on the covers, if any) a title
-          distinct from that of the Document, and from those of
-          previous versions (which should, if there were any, be listed
-          in the History section of the Document).  You may use the
-          same title as a previous version if the original publisher of
-          that version gives permission.
-
-       B. List on the Title Page, as authors, one or more persons or
-          entities responsible for authorship of the modifications in
-          the Modified Version, together with at least five of the
-          principal authors of the Document (all of its principal
-          authors, if it has fewer than five), unless they release you
-          from this requirement.
-
-       C. State on the Title page the name of the publisher of the
-          Modified Version, as the publisher.
-
-       D. Preserve all the copyright notices of the Document.
-
-       E. Add an appropriate copyright notice for your modifications
-          adjacent to the other copyright notices.
-
-       F. Include, immediately after the copyright notices, a license
-          notice giving the public permission to use the Modified
-          Version under the terms of this License, in the form shown in
-          the Addendum below.
-
-       G. Preserve in that license notice the full lists of Invariant
-          Sections and required Cover Texts given in the Document's
-          license notice.
-
-       H. Include an unaltered copy of this License.
-
-       I. Preserve the section Entitled "History", Preserve its Title,
-          and add to it an item stating at least the title, year, new
-          authors, and publisher of the Modified Version as given on
-          the Title Page.  If there is no section Entitled "History" in
-          the Document, create one stating the title, year, authors,
-          and publisher of the Document as given on its Title Page,
-          then add an item describing the Modified Version as stated in
-          the previous sentence.
-
-       J. Preserve the network location, if any, given in the Document
-          for public access to a Transparent copy of the Document, and
-          likewise the network locations given in the Document for
-          previous versions it was based on.  These may be placed in
-          the "History" section.  You may omit a network location for a
-          work that was published at least four years before the
-          Document itself, or if the original publisher of the version
-          it refers to gives permission.
-
-       K. For any section Entitled "Acknowledgements" or "Dedications",
-          Preserve the Title of the section, and preserve in the
-          section all the substance and tone of each of the contributor
-          acknowledgements and/or dedications given therein.
-
-       L. Preserve all the Invariant Sections of the Document,
-          unaltered in their text and in their titles.  Section numbers
-          or the equivalent are not considered part of the section
-          titles.
-
-       M. Delete any section Entitled "Endorsements".  Such a section
-          may not be included in the Modified Version.
-
-       N. Do not retitle any existing section to be Entitled
-          "Endorsements" or to conflict in title with any Invariant
-          Section.
-
-       O. Preserve any Warranty Disclaimers.
-
-     If the Modified Version includes new front-matter sections or
-     appendices that qualify as Secondary Sections and contain no
-     material copied from the Document, you may at your option
-     designate some or all of these sections as invariant.  To do this,
-     add their titles to the list of Invariant Sections in the Modified
-     Version's license notice.  These titles must be distinct from any
-     other section titles.
-
-     You may add a section Entitled "Endorsements", provided it contains
-     nothing but endorsements of your Modified Version by various
-     parties--for example, statements of peer review or that the text
-     has been approved by an organization as the authoritative
-     definition of a standard.
-
-     You may add a passage of up to five words as a Front-Cover Text,
-     and a passage of up to 25 words as a Back-Cover Text, to the end
-     of the list of Cover Texts in the Modified Version.  Only one
-     passage of Front-Cover Text and one of Back-Cover Text may be
-     added by (or through arrangements made by) any one entity.  If the
-     Document already includes a cover text for the same cover,
-     previously added by you or by arrangement made by the same entity
-     you are acting on behalf of, you may not add another; but you may
-     replace the old one, on explicit permission from the previous
-     publisher that added the old one.
-
-     The author(s) and publisher(s) of the Document do not by this
-     License give permission to use their names for publicity for or to
-     assert or imply endorsement of any Modified Version.
-
-  5. COMBINING DOCUMENTS
-
-     You may combine the Document with other documents released under
-     this License, under the terms defined in section 4 above for
-     modified versions, provided that you include in the combination
-     all of the Invariant Sections of all of the original documents,
-     unmodified, and list them all as Invariant Sections of your
-     combined work in its license notice, and that you preserve all
-     their Warranty Disclaimers.
-
-     The combined work need only contain one copy of this License, and
-     multiple identical Invariant Sections may be replaced with a single
-     copy.  If there are multiple Invariant Sections with the same name
-     but different contents, make the title of each such section unique
-     by adding at the end of it, in parentheses, the name of the
-     original author or publisher of that section if known, or else a
-     unique number.  Make the same adjustment to the section titles in
-     the list of Invariant Sections in the license notice of the
-     combined work.
-
-     In the combination, you must combine any sections Entitled
-     "History" in the various original documents, forming one section
-     Entitled "History"; likewise combine any sections Entitled
-     "Acknowledgements", and any sections Entitled "Dedications".  You
-     must delete all sections Entitled "Endorsements."
-
-  6. COLLECTIONS OF DOCUMENTS
-
-     You may make a collection consisting of the Document and other
-     documents released under this License, and replace the individual
-     copies of this License in the various documents with a single copy
-     that is included in the collection, provided that you follow the
-     rules of this License for verbatim copying of each of the
-     documents in all other respects.
-
-     You may extract a single document from such a collection, and
-     distribute it individually under this License, provided you insert
-     a copy of this License into the extracted document, and follow
-     this License in all other respects regarding verbatim copying of
-     that document.
-
-  7. AGGREGATION WITH INDEPENDENT WORKS
-
-     A compilation of the Document or its derivatives with other
-     separate and independent documents or works, in or on a volume of
-     a storage or distribution medium, is called an "aggregate" if the
-     copyright resulting from the compilation is not used to limit the
-     legal rights of the compilation's users beyond what the individual
-     works permit.  When the Document is included in an aggregate, this
-     License does not apply to the other works in the aggregate which
-     are not themselves derivative works of the Document.
-
-     If the Cover Text requirement of section 3 is applicable to these
-     copies of the Document, then if the Document is less than one half
-     of the entire aggregate, the Document's Cover Texts may be placed
-     on covers that bracket the Document within the aggregate, or the
-     electronic equivalent of covers if the Document is in electronic
-     form.  Otherwise they must appear on printed covers that bracket
-     the whole aggregate.
-
-  8. TRANSLATION
-
-     Translation is considered a kind of modification, so you may
-     distribute translations of the Document under the terms of section
-     4.  Replacing Invariant Sections with translations requires special
-     permission from their copyright holders, but you may include
-     translations of some or all Invariant Sections in addition to the
-     original versions of these Invariant Sections.  You may include a
-     translation of this License, and all the license notices in the
-     Document, and any Warranty Disclaimers, provided that you also
-     include the original English version of this License and the
-     original versions of those notices and disclaimers.  In case of a
-     disagreement between the translation and the original version of
-     this License or a notice or disclaimer, the original version will
-     prevail.
-
-     If a section in the Document is Entitled "Acknowledgements",
-     "Dedications", or "History", the requirement (section 4) to
-     Preserve its Title (section 1) will typically require changing the
-     actual title.
-
-  9. TERMINATION
-
-     You may not copy, modify, sublicense, or distribute the Document
-     except as expressly provided under this License.  Any attempt
-     otherwise to copy, modify, sublicense, or distribute it is void,
-     and will automatically terminate your rights under this License.
-
-     However, if you cease all violation of this License, then your
-     license from a particular copyright holder is reinstated (a)
-     provisionally, unless and until the copyright holder explicitly
-     and finally terminates your license, and (b) permanently, if the
-     copyright holder fails to notify you of the violation by some
-     reasonable means prior to 60 days after the cessation.
-
-     Moreover, your license from a particular copyright holder is
-     reinstated permanently if the copyright holder notifies you of the
-     violation by some reasonable means, this is the first time you have
-     received notice of violation of this License (for any work) from
-     that copyright holder, and you cure the violation prior to 30 days
-     after your receipt of the notice.
-
-     Termination of your rights under this section does not terminate
-     the licenses of parties who have received copies or rights from
-     you under this License.  If your rights have been terminated and
-     not permanently reinstated, receipt of a copy of some or all of
-     the same material does not give you any rights to use it.
-
- 10. FUTURE REVISIONS OF THIS LICENSE
-
-     The Free Software Foundation may publish new, revised versions of
-     the GNU Free Documentation License from time to time.  Such new
-     versions will be similar in spirit to the present version, but may
-     differ in detail to address new problems or concerns.  See
-     `http://www.gnu.org/copyleft/'.
-
-     Each version of the License is given a distinguishing version
-     number.  If the Document specifies that a particular numbered
-     version of this License "or any later version" applies to it, you
-     have the option of following the terms and conditions either of
-     that specified version or of any later version that has been
-     published (not as a draft) by the Free Software Foundation.  If
-     the Document does not specify a version number of this License,
-     you may choose any version ever published (not as a draft) by the
-     Free Software Foundation.  If the Document specifies that a proxy
-     can decide which future versions of this License can be used, that
-     proxy's public statement of acceptance of a version permanently
-     authorizes you to choose that version for the Document.
-
- 11. RELICENSING
-
-     "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
-     World Wide Web server that publishes copyrightable works and also
-     provides prominent facilities for anybody to edit those works.  A
-     public wiki that anybody can edit is an example of such a server.
-     A "Massive Multiauthor Collaboration" (or "MMC") contained in the
-     site means any set of copyrightable works thus published on the MMC
-     site.
-
-     "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
-     license published by Creative Commons Corporation, a not-for-profit
-     corporation with a principal place of business in San Francisco,
-     California, as well as future copyleft versions of that license
-     published by that same organization.
-
-     "Incorporate" means to publish or republish a Document, in whole or
-     in part, as part of another Document.
-
-     An MMC is "eligible for relicensing" if it is licensed under this
-     License, and if all works that were first published under this
-     License somewhere other than this MMC, and subsequently
-     incorporated in whole or in part into the MMC, (1) had no cover
-     texts or invariant sections, and (2) were thus incorporated prior
-     to November 1, 2008.
-
-     The operator of an MMC Site may republish an MMC contained in the
-     site under CC-BY-SA on the same site at any time before August 1,
-     2009, provided the MMC is eligible for relicensing.
-
-
-ADDENDUM: How to use this License for your documents
-====================================================
-
-To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and license
-notices just after the title page:
-
-       Copyright (C)  YEAR  YOUR NAME.
-       Permission is granted to copy, distribute and/or modify this document
-       under the terms of the GNU Free Documentation License, Version 1.3
-       or any later version published by the Free Software Foundation;
-       with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
-       Texts.  A copy of the license is included in the section entitled ``GNU
-       Free Documentation License''.
-
-   If you have Invariant Sections, Front-Cover Texts and Back-Cover
-Texts, replace the "with...Texts." line with this:
-
-         with the Invariant Sections being LIST THEIR TITLES, with
-         the Front-Cover Texts being LIST, and with the Back-Cover Texts
-         being LIST.
-
-   If you have Invariant Sections without Cover Texts, or some other
-combination of the three, merge those two alternatives to suit the
-situation.
-
-   If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License, to
-permit their use in free software.
