spec_math

This crate contains approximations for a set of mathematical functions commonly referred to as "special functions". The goal of this crate is to eventually contain a full Rust re-implementation of the CEPHES library with minimal changes in modules such as the cephes64 module. The special functions will also be available as traits for easier use in Rust, potentially with modifications to correct bugs or improve performance from the original CEPHES implementation.

Currently, the gamma functions, error functions, elliptic integrals, sine and cosine integrals, fresnel integrals, normal distribution, and bessel functions are implemented.
