Introduction

Mpfrcx is a library for the arithmetic of univariate polynomials over arbitrary precision real (Mpfr) or complex (Mpc) numbers, without control on the rounding. For the time being, only the few functions needed to implement the floating point approach to complex multiplication are implemented. On the other hand, these comprise asymptotically fast multiplication routines such as Toom–Cook and the FFT.

The library is written by Andreas Enge and is distributed under the Gnu Lesser General Public License, either version 2.1 of the licence, or (at your option) any later version.
