sollya

Sollya is both a tool environment and a library for safe floating-point code development. It offers a convenient way to perform computations with multiple precision interval arithmetic. It is particularly targeted to the automated implementation of mathematical floating-point libraries. Initially, Sollya was intended more specifically for people implementing numerical functions in mathematical libraries (e.g., exp, arccos, tanh, etc.). Since then, the tool has evolved and has now become interesting not only to developers of mathematical libraries, but also to everyone who needs to perform numerical experiments in an environment that is safe with respect to round-off errors. This package provides the command-line tool sollya.
