<interactive>:1:19: Ambiguous type variable `a' in the constraints: `Fractional a' arising from a use of `/' at <interactive>:1:19-44 `Integral a' arising from a use of `^' at <interactive>:1:20-24 Probable fix: add a type signature that fixes these type variable(s) ============================
Could somebody please throw some light?
Consider the types of both (^) and (/). Then take a look at https://www.haskell.org/onlinereport/haskell2010/haskell2x.png and compare with your error message. Note especially that there is no connection from Integral to Fractional or vice versa. As a solution use either the already suggested (**) or fromIntegral (mind the last subsection of https://www.haskell.org/onlinereport/haskell2010/haskellch6.html ) best, Max
