The GNU Octave [http://octave.sourceforge.net/interval/ interval package] provides data types and
fundamental operations for real valued interval arithmetic based on the common floating-point format “binary64” a. k. a. double- precision. It aims to be standard compliant with the (upcoming) [http://standards.ieee.org/develop/project/1788.html IEEE 1788] and therefore implements the ''set-based'' interval arithmetic flavor. '''Interval arithmetic''' produces mathematically proven numerical results.
