Floating Point Numbers

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 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...

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...

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...

logfloat is a Haskell module that presents a class for storing numbers in the log-domain. The main reason for doing this is to prevent underflow when multiplying many probabilities as is done in Hidden Markov Models. It is also helpful for preventing overflow.


Platforms: Mac

This Python module provides basic facilities for mathematics on fixed-point numbers. The number of fractional binary digits is tunable, allowing near-arbitrary precision arithmetic. Arithmetic & functions such as sqrt, exp, log, sin & cos are available.


Platforms: Windows, Mac, Linux

Converts binary data of any format in a string to floating point decimal of a defined fraction size.The "intsize" input parameter defines the size of the exponent and sets the fixed point location in the binary number. se accompani for test program for test of this function
