[...] I personally prefer the Python solution, where we have two operators with the same behaviour over all the numbers. In Haskell, something like (/) :: (Num a, Real b) => a -> a -> b
This should be (/) :: (Num a, Fractional b) => a -> a -> b
but I'm not sure it is correct.
(//) :: (Num a, Integral b) => a -> a -> b
