The list found at http://haskell.org/libraries/#numerics
might be a good starting point for finding what you need. I can recommend the "DoCon" library, which is pretty sophisticated. Another good choice might be the crypto library available at: http://www.haskell.org/crypto/ It also includes several number theory modules and is arguably somewhat simpler to use than DoCon is.
