mp++ is a C++11 library for multiprecision arithmetic, currently supporting arbitrary-precision integers,
rationals and floats, and quadruple-precision floats.

Based on well-known libraries such as [GMP](https://gmplib.org/), [MPFR](http://www.mpfr.org), and others,
mp++ was initially conceived as a [GMP](https://gmplib.org/) wrapper with a 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](https://bluescarni.github.io/mppp/benchmarks.html) section of the documentation).
The price to pay is a small overhead when operating on large integers.

Eventually, a multiprecision rational class and two multiprecision floating-point classes were added, and today a secondary objective
of mp++ is to provide a modern, consistent and unified C++ interface to several lower-level multiprecision libraries.

mp++ is a spinoff of the [Piranha](https://github.com/bluescarni/piranha) library, released under the
[MPL2](https://www.mozilla.org/en-US/MPL/2.0/FAQ/) license.
