2013-09-06	math: remove STRICT_ASSIGN from exp2f (see previous commit)	Szabolcs Nagy	-1/+1

2013-09-05	math: fix underflow in exp*.c and long double handling in exp2l	Szabolcs Nagy	-28/+24
	* don't care about inexact flag * use double_t and float_t (faster, smaller, more precise on x86) * exp: underflow when result is zero or subnormal and not -inf * exp2: underflow when result is zero or subnormal and not exact * expm1: underflow when result is zero or subnormal * expl: don't underflow on -inf * exp2: fix incorrect comment * expm1: simplify special case handling and overflow properly * expm1: cleanup final scaling and fix negative left shift ub (twopk)
2012-12-16	math: use 0x1p-120f and 0x1p120f for tiny and huge values	Szabolcs Nagy	-2/+2
	previously 0x1p-1000 and 0x1p1000 was used for raising inexact exception like x+tiny (when x is big) or x+huge (when x is small) the rational is that these float consts are large enough (0x1p-120 + 1 raises inexact even on ld128 which has 113 mant bits) and float consts maybe smaller or easier to load on some platforms (on i386 this reduced the object file size by 4bytes in some cases)
2012-11-17	math: cleanup exp2.c exp2f.c and exp2l.c	Szabolcs Nagy	-16/+14
	* old code relied on sign extension on right shift * exp2l ld64 wrapper was wrong * use scalbn instead of bithacks
2012-03-18	fix loads of missing const in new libm, and some global vars (?!) in powl	Rich Felker	-1/+1

2012-03-13	first commit of the new libm!	Rich Felker	-0/+130
	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.
