Comment (by tristes_tigres):

 Correctly implemented FP would be actually faster on (most) modern
 processors, because they implement IEEE754 in hardware.

 By the way, the whole model of FP computations in Haskell needs to be
 rethought from scratch. FP operations are influenced by the state of
 rounding flags and may raise exceptions, but Haskell type system treats
 them as pure.
