# Software products

There are several software products developed by our group.

## The continued fractions for special functions package (CFSF)

The **continued fractions for special functions package (CFSF)** complements a systematic study of continued fraction representations for special functions. It provides all the functionality to create continued fractions, in particular k-periodic or limit k-periodic fractions, to compute approximants, make use of continued fraction tails, perform equivalence transformations and contractions, and much more. The package, developed in Maple, includes a library of more than 200 representations of special functions, of which only 10% can be found in the NBS Handbook of Mathematical Functions with Formulas, Graphs and mathematical Tables by Abramowitz and Stegun.

## IEEE 754 Compliance Checker (IEEECC754)

**IeeeCC754**, or **IEEE 754 Compliance Checker,** is a precision and range independent tool to test whether an implementation of floating-point arithmetic (in hardware or software) is compliant with the principles of the IEEE 754/854 floating-point standard. It is being re-developed for the newest IEEE 754-2008 standard.

## IEEE-compliant mixed precision floating-point arithmetic library (libMpIeee)

**libMpIeee** is a C++ software library for radix 2^{n} or 10^{m} mixed precision floating-point arithmetic, that is fully compliant with the IEEE 754/854 standards for floating-point arithmetic. In addition, the exact rounding from and to decimal is supported without restrictions on the exponent or mantissa range.
