2013-09-05math: cosmetic cleanup (use explicit union instead of fshape and dshape)Szabolcs Nagy-13/+12
2012-11-13math: fix nextafter and nexttoward on maxdbl and maxflt inputSzabolcs Nagy-1/+1
old code (return x+x;) returns correct value and raises correct flags only if the result is stored as double (or float)
2012-05-06add FORCE_EVAL macro to evaluate float expr for their side effectnsz-4/+2
updated nextafter* to use FORCE_EVAL, it can be used in many other places in the math code to improve readability.
2012-05-06fix unused variable warnings in new nextafter/nexttoward codeRich Felker-1/+2
apparently initializing a variable is not "using" it but assigning to it is "using" it. i don't really like this fix, but it's better than trying to make a bigger cleanup just before a release, and it should work fine (tested against nsz's math tests).
2012-05-06math: nextafter and nexttoward cleanupnsz-53/+28
make nexttoward, nexttowardf independent of long double representation. fix nextafterl: it did not raise underflow flag when the result was 0.
2012-03-13first commit of the new libm!Rich Felker-0/+62
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.
