Interval Arithmetic

Is there an interval arithmetic library in D? I couldn’t find one. In case I had to write my own, I understand that the IEEE standard floating point arithmetic provides operations for rounding up or down certain operations like summing, subtracting, etc. (thus overriding the default behavior
