Dear Oliver,

Yes, this might be the way. In MATLAB I got around my rounding problem
by using Sigfried Rump's interval toolbox INTLAB. Many thanks for your
suggestion, and thanks to the Octave community for their amazing

Best regards,



you are welcome. Since you know INTLAB, please check whether the free Octave interval package is a valid replacement for your project. If you are missing some functionality in the interval package, please let me know.

You can find many functions with directed rounding here (no need to change the rounding mode yourself):

P.S. The Octave interval package is conforming to the IEEE standard for interval arithmetic. It might behave differently compared to INTLAB, especially on empty intervals.
