Bruce Evans 94a5f9be99 Use only double precision for "kernel" tanf (except for returning float). ... This is a minor interface change. The function is renamed from __kernel_tanf() to __kernel_tandf() so that misues of it will cause link errors and not crashes. This version is a routine translation with no special optimizations for accuracy or efficiency. It gives an unimportant increase in accuracy, from ~0.9 ulps to 0.5285 ulps. Almost all of the error is from the minimax polynomial (~0.03 ulps and the final rounding step (< 0.5 ulps). It gives strange differences in efficiency in the -5 to +10% range, with -O1 fairly consistently becoming faster and -O2 slower on AXP and A64 with gcc-3.3 and gcc-3.4.		2005-11-23 14:27:56 +00:00
