2025-01-02new inputs with large errors for [a]cospi, [a]sinpi, [a]tanpi, atan2piPaul Zimmermann1-0/+676
These inputs were generated with the programs from https://gitlab.inria.fr/zimmerma/math_accuracy, with rounding to nearest: * for univariate binary32 functions by exhaustive search * for other functions with the "threshold" parameter up to 10^6
2024-12-12Implement C23 atan2piJoseph Myers1-0/+14205
C23 adds various <math.h> function families originally defined in TS 18661-4. Add the atan2pi functions (atan2(y,x)/pi). Tested for x86_64 and x86, and with build-many-glibcs.py.
