Re: [Haskell-cafe] Pure Haskell implementation of Float type?

There's the numbers package which contains BigFloat. You can pick your own precision, but it's not IEEE. It's actually base 10 floats which makes it more fun (actually, the iEEE standard will cover base 10 floats in the future).

Actually, all of the arbitrary precision real number implementations may be of interest for you: http://haskell.org/haskellwiki/Applications_and_libraries/Mathematics#Number... The NumericPrelude implementation by me, however, sometimes uses the Double implementation for speedup.
