The GNU Octave | The GNU Octave built-in floating-point routines are not useful for interval arithmetic: Their results depend on hardware, system libraries and compilation options. | ||
The interval package handles all arithmetic functions with the help of the [http://www.mpfr.org/ GNU MPFR library]. With MPFR it is possible to compute system-independent, valid and tight enclosures of the correct results. | The interval package handles all arithmetic functions with the help of the [http://www.mpfr.org/ GNU MPFR library].
