[Haskell-beginners] Retrieving the decimal portion of a Double

    Hi all,     I am trying to retrieve the decimal portion of a Double. My code is:     getDecimal x = x - floor(x)     I would expect the following:     Main> getDecimal 1.23     0.23 :: [Double]     but instead, I get:     Main> getDecimal 1.23     ERROR - Unresolved overloading     *** Type       : (RealFrac a, Integral a) => a     *** Expression : getDecimal 1.23     I have tried adding "getDecimal :: Double -> Double" but it only causes the following message to appear:     ERROR file:C:\Documents and Settings\User\file.hs:60 - Instance of Integral Double required for definition of getDecimal     How should I define my function so that it'll work? Thanks!     Regards,     Dom
