"The MPFR library is a C library for multiple-precision floating-point computations with exact rounding (also called correct rounding). It is based on the GMP multiple-precision library. The main goal of MPFR is to provide a library for multiple-precision floating-point computation which is both efficient and has well-defined semantics. It copies the good ideas from the ANSI/IEEE-754 standard for double-precision floating-point arithmetic (53-bit mantissa)."


"GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. There is no practical limit to the precision except the ones implied by the available memory in the machine GMP runs on. GMP has a rich set of functions, and the functions have a regular interface."


"MPC is a library for the arithmetic of complex numbers with arbitrary precision and correct rounding of the result to the precision of the target variable. It is built upon and follows the same principles as mpfr. It is written by Paul Zimmermann, Patrick PĂ©lissier and Andreas Enge and distributed under the Gnu Lesser General Public License."
