*	math: fix sinh overflows in non-nearest rounding	Szabolcs Nagy	2020-02-21	1	-2/+3
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	The final rounding operation should be done with the correct sign otherwise huge results may incorrectly get rounded to or away from infinity in upward or downward rounding modes. This affected sinh and sinhf which set the sign on the result after a potentially overflowing mul. There may be other non-nearest rounding issues, but this was a known long standing issue with large ulp error (depending on how ulp is defined near infinity). The fix should have no effect on sinh and sinhf performance but may have a tiny effect on cosh and coshf.

*	first commit of the new libm!	Rich Felker	2012-03-13	1	-0/+51
	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.
