faster lrint and llrint functions A faster workaround for spurious inexact exceptions when the result cannot be represented. The old code actually could be wrong, because gcc reordered the integer conversion and the exception check. 2012-03-18 19:27:39 +01:00			`#include <math.h>`
first commit of the new libm! thanks to the hard work of Szabolcs Nagy (nsz), identifying the best (from correctness and license standpoint) implementations from freebsd and openbsd and cleaning them up! musl should now fully support c99 float and long double math functions, and has near-complete complex math support. tgmath should also work (fully on gcc-compatible compilers, and mostly on any c99 compiler). based largely on commit 0376d44a890fea261506f1fc63833e7a686dca19 from nsz's libm git repo, with some additions (dummy versions of a few missing long double complex functions, etc.) by me. various cleanups still need to be made, including re-adding (if they're correct) some asm functions that were dropped. 2012-03-13 01:17:53 -04:00
