Remember that internally arithmetic is binary, and that 0.1 can't be expressed exactly as a floating point number. I think that's the explanation. > Ok, ok, it is no bug... No, I think it is a bug: 0.1 ought to be equivalent to fromRational (1%10), but Hugs isn't intended for numerical work. GHCi gets the right answer.
