2013-09-05math: fix remaining old long double code (erfl, fmal, lgammal, scalbnl)Szabolcs Nagy-4/+4
in lgammal don't handle 1 and 2 specially, in fma use the new ldshape union instead of ld80 one.
2013-08-15math: minor scalbn*.c simplificationSzabolcs Nagy-2/+2
2012-03-19code cleanup of named constantsnsz-1/+1
zero, one, two, half are replaced by const literals The policy was to use the f suffix for float consts (1.0f), but don't use suffix for long double consts (these consts can be exactly represented as double).
2012-03-19simplify scalbn*.c implementationsnsz-49/+22
The old scalbn.c was wrong and slow, the new one is just slow. (scalbn(0x1p+1023,-2097) should give 0x1p-1074, but the old code gave 0)
2012-03-13first commit of the new libm!Rich Felker-0/+63
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.
