GHC's new code generator does some incredible stuff with the code for Float's RealFrac instance, properFraction has become about _seven times_ faster, floor and ceiling about _thirteen times_ and round about _10.5 times_ (values for my box, the exact numbers will differ, but the tendency will be the same).
Out of curiosity, by new code generator, are you meaning just the stock GHC 7 code path or are you meaning the new now available but disabled by default unless you use some flag (which I forget right now) code generation path. Cheers! -Tyson
