# 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.

LGPLv3+ for the code and GFDLv1.3+ (with no invariant sections) for the documentation.

## Special Update/Build Instructions¶

• mpc_mul_faster.patch: Patch from Paul Zimmermann to speed up MPC multiplication (for small precisions) by reducing overhead in MPFR operations.
