2016-10-20	math: fix pow signed shift ub	Szabolcs Nagy	-2/+2
	j is int32_t and thus j<<31 is undefined if j==1, so j is changed to uint32_t locally as a quick fix, the generated code is not affected. (this is a strict conformance fix, future c standard may allow 1<<31, see DR 463. the bug was inherited from freebsd fdlibm, the proper fix is to use uint32_t for all bit hacks, but that requires more intrusive changes.) reported by Daniel Sabogal
2015-04-18	math: fix pow(+-0,-inf) not to raise divbyzero flag	Szabolcs Nagy	-1/+1
	this reverts the commit f29fea00b5bc72d4b8abccba2bb1e312684d1fce which was based on a bug in C99 and POSIX and did not match IEEE-754 http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1515.pdf
2013-08-15	math: fix pow(x,-1) to raise underflow properly	Szabolcs Nagy	-2/+14
	if FLT_EVAL_METHOD!=0 check if (double)(1/x) is subnormal and not a power of 2 (if 1/x is power of 2 then either it is exact or the long double to double rounding already raised inexact and underflow)
2013-08-15	math: fix pow(0,-inf) to raise divbyzero flag	Szabolcs Nagy	-1/+1

2012-03-20	clean up pow.c and powf.c	nsz	-36/+29
	fix comments about special cases
2012-03-19	code cleanup of named constants	nsz	-20/+17
	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).
2012-03-13	math cleanup: use 1.0f instead of 1.0F	nsz	-1/+1

2012-03-13	first commit of the new libm!	Rich Felker	-0/+326
	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.
