mp++ is a C++11/14/17/20 library for multiprecision arithmetic, featuring:
quadruple-precision complex numbers,
arbitrary-precision complex numbers.
Design goals include:
excellent performance for small integer and rational operands,
easy embeddability in computer algebra systems and generic C++ libraries,
a large collection of arbitrary-precision special functions,
an ergonomic API based on modern C++ idioms.
Design non-goals include:
support for fixed-size wide integrals (i.e., no
uint512_t, try Boost Multiprecision instead).
Built on top of the GNU multiprecision stack (GMP, MPFR, MPC), mp++ was initially conceived as a GMP wrapper with special focus on performance with small operands. In particular, a small buffer optimisation and custom implementations of basic mathematical primitives are instrumental in achieving a performance increase, with respect to GMP and other integer multiprecision libraries, which can be substantial (see the benchmarks section).
Over time, mp++ has accrued many additional features, including multiprecision real and complex number types, and an expanding library of special functions (built in part on top of the excellent Arb library).
mp++ is a spinoff of the Piranha library, released under the MPL2 license. If you are using mp++ as part of your research, teaching, or other activities, we would be grateful if you could star the repository and/or cite our work.

mp++ is under active development, and, although we try not to break the API gratuitously, backwards-incompatible changes do happen from time to time. The API will be stabilised with the upcoming release of version 1.0.
This documentation refers to the latest development version of mp++, and it may describe features not yet available in mp++’s stable releases.
