Interval arithmetic

Hi all,

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.

Bye
Jonas
