musl/src/math/fmodf.c, branch v1.2.6 musl - an implementation of the standard library for Linux-based systems math: rewrite remainder functions (remainder, remquo, fmod, modf) 2013-09-05T11:30:07+00:00 Szabolcs Nagy nsz@port70.net 2013-09-03T04:09:12+00:00 ee2ee92d62c43f6658d37ddea4c316d2089d0fe9 * results are exact * modfl follows truncl (raises inexact flag spuriously now) * modf and modff only had cosmetic cleanup * remainder is just a wrapper around remquo now * using iterative shift+subtract for remquo and fmod * ld80 and ld128 are supported as well 
* results are exact
* modfl follows truncl (raises inexact flag spuriously now)
* modf and modff only had cosmetic cleanup
* remainder is just a wrapper around remquo now
* using iterative shift+subtract for remquo and fmod
* ld80 and ld128 are supported as well
don't try to create non-standard denormalization signal 2012-03-19T22:30:45+00:00 nsz nsz@port70.net 2012-03-19T22:30:45+00:00 4caa17b2a17d136efedfb63fceef832401063d70 Underflow exception is only raised when the result is invalid, but fmod is always exact. x87 has a denormalization exception, but that's nonstandard. And the superflous *1.0 will be optimized away by any compiler that does not honor signaling nans.

first commit of the new libm! 2012-03-13T05:17:53+00:00 Rich Felker dalias@aerifal.cx 2012-03-13T05:17:53+00:00 b69f695acedd4ce2798ef9ea28d834ceccc789bd 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.
