mpc: Arithmetic of complex numbers with arbitrarily high precision and correct rounding
=======================================================================================

Description
-----------

From http://www.multiprecision.org/mpc: GNU MPC is a C library for the
arithmetic of complex numbers with arbitrarily high precision and
correct rounding of the result. It extends the principles of the
IEEE-754 standard for fixed precision real floating point numbers to
complex numbers, providing well-defined semantics for every operation.
At the same time, speed of operation at high precision is a major design
goal.
