Remember, the notion of inexactness is a taint, not an intrinsic property of a type. Even the Scheme numeric tower recognizes this. LIkewise, the decimal specification also spells-out this notion as basic to its design.
I'm not sure it really does, otherwise every decimal value would have a flag indicating whether it was tainted with inexactness, and this flag would propagate through calculations. -- Greg
