Re: [Haskell-cafe] Re: Double -> CDouble, realToFrac doesn't work

Why is there no Irrational class. This would make more sense for Floats and Doubles than the fraction based Rational class. We could also add an implementation of infinite precision irrationals using a pair of Integers for exponent and mantissa.

That would just be a subset of the rationals, namely the dyadic rationals (mantissa / 2^^exponent). -- Ben
