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... Platforms: *nix

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. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This graphical tool displays an editable binary representation of the two floating point formats used in MATLAB, namely single and double.For the selected number three displays are available:* The value as formated by the MATLAB software* The analysis of its segments: sign, mantissa and exponent...

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... Platforms: Mac

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... Platforms: Matlab

APFP (Arbitrary Precision Floating Point) is an Unicon class for performing arbitrary precision floating point calculations. It also includes a class for calculating with arbitrary precision complex numbers. APFP requires unicon overloaded operators. Whats New in This Release: - Made to use... Platforms: *nix

Strings edit is a library that provides I/O facilities for integer, floating-point, Roman numbers, and strings. Both input and output subroutines support string pointers for consequent stream processing. The output can be aligned in a fixed size field with padding. Numeric input can be checked... Platforms: *nix

LAoE is a rich featured graphical audiosample editor, based on multi layers, floating point samples. LAoE means Layer-based Audio Editor, and it is a rich featured graphical audiosample-editor, based on multi-layers, floating-point samples, volume-masks, variable selection-intensity, and many... Platforms: *nix

This script eliminates completely  rounding errors and loss of significance due to catastrophic cancellation during summation. It  achieves exactness by keeping full precision intermediate subtotals. Offers three alternative approaches, each using a different technique to store exact... Platforms: Windows, Mac, *nix, Python, BSD Solaris

This class readily reproduces textbook examples and provides immediate demonstrations of representation error, loss of precision (subtractive cancellation), and the failure of the distributive, commutative, and associative laws. Beyond textbook work, this class is also useful for exploring the... Platforms: Windows, Mac, *nix, Python, BSD Solaris
