hi,

does axiom support any kind of interval arithmetic. An interval datatype or 
something? I can't find any hint within the documentation.

Example:

  x : IntervalType := [-2, 2]
  y : IntervalType := [.75, 1.4]

    x + y       =>   [-1.25, 3.4]
    x - y       =>   [-3.4, 1.25]
    x * y       =>   [-2.8, 2.8]
    square(x)   =>   [0, 4]



Thanks
Joke
