The algorithm is intentended for efficient evaluation +utilizing SIMD instruction sets like SSE or AVX, but it is also fast +using usual scalar operations. + +The package contains a few directories in which implementation in the +corresponding languages are contained. You can run "make test" in +order to test the functions in each directory. + +The software is in public domain. You can use the software without any +obligation. + + +Author : Naoki Shibata + +Main download page : http://shibatch.sourceforge.net/ + + + +History + +2.80 Added support for ARM NEON. Added higher accuracy single +precision functions : sinf_u1, cosf_u1, sincosf_u1, tanf_u1, asinf_u1, +acosf_u1, atanf_u1, atan2f_u1, logf_u1, and cbrtf_u1. + +2.70 Added higher accuracy functions : sin_u1, cos_u1, sincos_u1, +tan_u1, asin_u1, acos_u1, atan_u1, atan2_u1, log_u1, and +cbrt_u1. These functions evaluate the corresponding function with at +most 1 ulp of error. + +2.60 Added the remaining single precision functions : powf, sinhf, +coshf, tanhf, exp2f, exp10f, log10f, log1pf. Added support for FMA4 +(for AMD Bulldozer). Added more test cases. Fixed minor bugs (which +degraded accuracy in some rare cases). + +2.50 Added support for AVX2. SLEEF now compiles with ICC. + +2.40 Fixed incorrect denormal/nonnumber handling in ldexp, ldexpf, +sinf and cosf. Removed support for Go language. + +2.31 Added sincosf. + +2.30 Added single precision functions : sinf, cosf, tanf, asinf, +acosf, atanf, logf, expf, atan2f and cbrtf. + +2.20 Added exp2, exp10, expm1, log10, log1p, and cbrt. + +2.10 asin() and acos() are back. Added ilogb() and ldexp(). Added +hyperbolic functions. Eliminated dependency on frexp, ldexp, fabs, +isnan and isinf. + +2.00 All of the algorithm has been updated. Both accuracy and speed +are improved since version 1.10. Denormal number handling is also +improved. + +1.10 AVX support is added. Accuracy tester is added. + +1.00 Initial release |
