2013-09-05math: ilogb cleanupSzabolcs Nagy-6/+8
* consistent code style * explicit union instead of typedef for double and float bit access * turn FENV_ACCESS ON to make 0/0.0f raise invalid flag * (untested) ld128 version of ilogbl (used by logbl which has ld128 support)
2012-11-12math: raise invalid flag in ilogb*.c on +-0, +-inf and nanSzabolcs Nagy-2/+6
2012-03-13remove libm.h includes when math.h and float.h are enoughnsz-1/+0
2012-03-13first commit of the new libm!Rich Felker-0/+21
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.
