Usage

To use SLEEF.jl

julia> Pkg.add("SLEEF")
julia> using SLEEF

julia> SLEEF.exp(3.0)
20.085536923187668

julia> SLEEF.exp(3f0)
20.085537f0

The available functions include (within 1 ulp)

sin, cos, tan, asin, acos, atan, sincos, sinh, cosh, tanh,
    asinh, acosh, atanh, log, log2, log10, log1p, ilogb, exp, exp2, exp10, expm1, ldexp, cbrt, pow

Faster variants (within 3 ulp)

sin_fast, cos_fast, tan_fast, sincos_fast, asin_fast, acos_fast, atan_fast, atan2_fast, log_fast, cbrt_fast

Notes

The trigonometric functions are tested to return values with specified accuracy when the argument is within the following range:

  • Double (Float64) precision trigonometric functions : [-1e+14, 1e+14]
  • Single (Float32) precision trigonometric functions : [-39000, 39000]
