   Hi,

   Is there a function to get that? I'm using

\x -> x - fromIntegral(floor x)

since I was not able to find something better, but I guess I have missed
something in the standard library since there are functions with similar
funcionality.
How about
frac :: RealFrac a => a -> a
frac = snd . properFraction

However, this leaves the type of the integral part unspecified.

  I've just found mod', a version of mod that works with reals (so I 
could use mod' x 1.0), in module Data.Fixed. However, trying to load 
Data.Fixed in ghci says that module doesn't exist (ghc 6.6).
