# 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)

```julia

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)

 ```julia

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]`
