Oh yes, that is absolutely what Haskell does for Rationals. The 'read' and 'show' for Rational uses the % notation. No proposed change here. The point is instead this: if you specifically want to read a Rational from a string like "3.24", which is perfectly reasonable (324 % 100), then the same function (readFloat) should do it as read a Float from the string in that format. That's what type-class overloading is for. Simon _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
