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, MPFR, and others, mp++ was initially
|
|
conceived as a GMP 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 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
