Overview
MPFRCPP is free object-oriented interface to the MPFR library written in C++. MPFR provides arbitrary precision arithmetic on floating-point numbers. MPFRCPP represents floating point numbers as objects and overloads operators / functions to make using of MPFR in OO-programs easier.
The distribution package includes Numeric Analysis / Computer Research C++ Classes with implementation of rational numbers, polynomials (including orthogonal polynomials) and complex numbers. Interval aritmetics could be used via included boost::numeric::interval_lib specification for library type.
MPFRCPP supports
- exponential, logarithmic, trigonometric, inverse trigonometric, hyperbolic, inverse hyperbolic, integer-related functions;
- special functions: first and second order Bessel functions of order 1 and n, exponential integral, error function, complementary error function, Gamma function, Gamma function logarithm, Riemann Zeta function;
- numeric constants: log 2 (0.693…), pi (3.141…), Euler-Mascheroni (0.577…), Catalan (0.915…);
- random numbers: Mersenne Twister and linear congruental algorithm.
Current Work
- Now MPFRCPP wraps MPFR 2.3.0, the new MPFR version.
- I am working on GMP / MPFR wrappers for Java. They will not be compatible with MPFRCPP. As for C++ code, I don't plan to drop maintenance, but I'll focus on Java work, so MPFRCPP will not be refactored (seriously improved), only critical bug fixes and updates to further MPFR versions are expected.
