Hi Folks, Here is a function that takes a pair of Integral values and divides them: divide_v1 :: Integral a => (a, a) -> a divide_v1 (m, n) = (m + n) `div` 2 I invoke the function with a pair of Integral values and it works as expected: divide_v1 (1, 3) Great. That's perfect if my numbers are always Integrals. Here is a function that takes a pair of Fractional values and divides them: divide_v2 :: Fractional a => (a, a) -> a divide_v2 (m, n) = (m + n) / 2 I invoke the function with a pair of Fractional values and it works as expected: divide_v2 (1.0, 3.0) Great. That's perfect if my numbers are always Fractionals. I would like a function that works regardless of whether the numbers are Integrals or Fractionals: divide_v3 :: Num a => (a, a) -> a divide_v3 (m, n) = (m + n) ___ 2 What operator do I use for ___? Thanks. /Roger
