Floating Point Support

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...

This script achieves exactness by manipulating values stored as a long integer mantissa with an integer exponent (base two). All arithmetic operations are exact except for division which has regular floating point precision.

Dfp is a radix 10000 floating point math library. It features compile-time defineable precision, usual arithmetic functions (add, subtract, multiply, divide, etc.), and a set of mathematical functions including: natural logarithm and exponential, trigonometic functions and their inverses. Dfp...

An essential step in embedded software development, floating- to fixed-point conversion can be tedious, labor-intensive, and error-prone. System engineers frequently design algorithms in floating-point math, usually double-precision. This format represents the ideal algorithm behavior but takes...
