Abstract

I present a lightweight C++ library for the evaluation of classical polylogarithms Li_n and the special function Li_{22} for arbitrary complex arguments. The evaluation is possible in arbitrary precision arithmetic and features also an explicit double precision implementation for a much faster numerical evaluation. The implementation is based on arXiv:1601.02649.
