[Haskell-cafe] coercion to Int

what coercion can i use to get the below program to compile? i see class (Real a, Fractional a) => RealFrac a where round :: (Integral b) => a -> b and class (Fractional a) => Floating a where sqrt :: a -> a various combinations of fromInteger, toInteger do not help. fnK_ :: Int -> Int fnK_ x = round (sqrt x) -- line 2 Hugs session for: H:\Program Files\Hugs98\lib\Prelude.hs Prelude> :load xva Reading file "xva.hs": Type checking ERROR "xva.hs":2 - Instances of (RealFrac Int, Floating Int) required for definition of fnK_ __________________________________ Do you Yahoo!?
