It was a example, yeah I want to compute on intervals.

If you prefer another example [c]=[a]+[b]
> c.min = a.min \+/ b.min
> c.max = a.max /+\ b.max

\+/ and /+\ are + operator with rounding downward for the first and
upward for the second.

And my question is the same : how I do this operator (\+/ and /+\).
