(Incidentally, if it's any help in working out how this Rational was computed, the denominator is 2^27.) > Prelude> 13421773/134217728 > 0.1 Also allowed for the same reason. > Ok, ok, it is no bug... No, but this might be: Prelude> 13421773/134217728 - 0.1 1.4901161138336505e-9 I think that the language spec is sufficiently vague on this point that Hugs' behaviour is reasonable. When using floating point, you have to work with the numeric error rather than ignore it.
