I once again point out that realToFrac is *wrong* for converting from Float or Double.

Yes, I understand what you are saying and agree with you. But there is nothing better in the standard library
don't know whether you consider GHC as standard library, but if you do...: import GHC.Types import GHC.Prim -- | Double to Float d2f (D# d) = F# (double2Float# d) -- | Float to Double f2d (F# f) = D# (float2Double# f) ghci> f2d (1/0) Infinity it :: Double :) -- Daniel
