I am interested in interval arithmetic.
Does anyone know something about haskell implementations in this domain?
It would be nice to have a datatype Interval with the elementary operations {+,-,*,/}, where
>+ :: Intervall -> Intervall -> Intervall >(a,b) + (c,d) = (a+c,b+d)
>- :: Intervall -> Intervall -> Intervall >(a,b) - (c,d) = (a-d,b-c)
etc.
