This rule avoids the âdriftâ 503 503 phenomenon mentioned by Knuth in volume 2 of The Art of Computer 504 504 Programming (Section 4.2.2). 505 505 506 506 Most MPFR functions take as first argument the destination variable, 507 507 as second and following arguments the input variables, as last argument 508 508 a rounding mode, and have a return value of type âintâ, called the 509 "ternary value".
