bde 2005-11-12 18:20:09 UTC FreeBSD src repository Modified files: lib/msun/src e_logf.c Log: As for the float trig functions, use a minimax polynomial that is specialized for float precision. The new polynomial has degree 8 instead of 14, and a maximum error of 2**-34.34 (absolute) instead of 2**-30.66. This doesn't affect the final error significantly; the maximum error was and is about 0.8879 ulps on amd64 -01. The fdlibm expf() is not used on i386's (the "optimized" asm version is used), but probably should be since it was already significantly faster than the asm version on athlons. The asm version has the advantage of being more accurate, so keep using it for now. Revision Changes Path 1.8 +7 -9 src/lib/msun/src/e_logf.c
