*	math: fix expm1f overflow threshold	Szabolcs Nagy	2021-02-10	1	-2/+1
\| \| \| \| \| \| \| \| \|	the threshold was wrong so expm1f overflowed to inf a bit too early and on most targets uint32_t compare is faster than float compare so use that. this also fixes sinhf incorrectly returning nan for some values where the internal expm1f overflowed.
*	math: remove STRICT_ASSIGN macro	Szabolcs Nagy	2013-09-06	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	gcc did not always drop excess precision according to c99 at assignments before version 4.5 even if -std=c99 was requested which caused badly broken mathematical functions on i386 when FLT_EVAL_METHOD!=0 but STRICT_ASSIGN was not used consistently and it is worked around for old compilers with -ffloat-store so it is no longer needed the new convention is to get the compiler respect c99 semantics and when excess precision is not harmful use float_t or double_t or to specialize code using FLT_EVAL_METHOD
*	math: fix underflow in exp*.c and long double handling in exp2l	Szabolcs Nagy	2013-09-05	1	-39/+26
\| \| \| \| \| \| \| \| \| \| \| \|	* 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)
*	code cleanup of named constants	nsz	2012-03-19	1	-8/+7
\| \| \| \| \| \| \|	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).
*	math cleanup: use 1.0f instead of (float)1.0	nsz	2012-03-13	1	-11/+11

*	first commit of the new libm!	Rich Felker	2012-03-13	1	-0/+125
	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.
