| 2013年09月05日 | math: cosmetic cleanup (use explicit union instead of fshape and dshape) | Szabolcs Nagy | -17/+13 |
|
| 2012年11月13日 | math: fix nextafter and nexttoward on maxdbl and maxflt input | Szabolcs 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年05月06日 | add FORCE_EVAL macro to evaluate float expr for their side effect | nsz | -4/+2 |
|
updated nextafter* to use FORCE_EVAL, it can be used in many other
places in the math code to improve readability.
|
| 2012年05月06日 | fix unused variable warnings in new nextafter/nexttoward code | Rich 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年05月06日 | math: nextafter and nexttoward cleanup | nsz | -70/+27 |
|
make nexttoward, nexttowardf independent of long double representation.
fix nextafterl: it did not raise underflow flag when the result was 0.

| 2012年03月13日 | first commit of the new libm! | Rich Felker | -0/+79 |
|
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.
