Did you try fromIntegral?
fromIntegral :: (Integral a, Num b) => a -> b
fnK_ :: Int -> Int
fnK_ x = round (sqrt x) -- line 2
--
Thomas
fnK_ :: Int -> Int
fnK_ = round . sqrt . fromIntegral

i see
class (Real a, Fractional a) => RealFrac a where
round :: (Integral b) => a -> b
and
class (Fractional a) => Floating a where
sqrt
James,
Untested:
fnK_ :: Int -> Int
fnK_ n = round (sqrt $ fromInteger x :: Double)
