Overview

mathslib is a compilation of Mathematical Functions and Algorithms. Unless credit was given all of the functions were written by me. Relevant articles are also linked where the implementation is complex.

I have used most of these for Project Euler.

See my website ivl-projecteuler.com for their implementation
