Re: type classes and generality

Ah, now I think I understand your problem. You want to `random' to generate random numbers that span all the possible values of the type within the range [0, 1], or at least a substantial subset, but the "Real" class doesn't let you generate any numbers other than integers. The above approach will give you random numbers from `random', but they will only ever be 0 or 1, so maybe they are not as random as you needed! ;-)

Each pseudorandom generator generates a countable sequence of values, which is isomorphic to a sequence of integers. In good old (Turbo)C we got something between 0 and MAXINT and then divided by (double)MAXINT. Can't _this_ be done in Haskell? Alexander
