but keep getting type conversion errors.
module Main where
ageJudge :: (Integral a) => a -> String ageJudge age | age >= 40 = "You're too old!" | age <= 30 = "Your too young" | otherwise = "Not in the programming age range.."
main = do putStrLn "What is your name?" name <- getLine putStrLn ("Nice to meet you, " ++ name ++ "!") putStrLn "What is your age?" age <- getLine let inpIntegral = (read age)::Double -- let decission = ageJudge (read inpIntegral)::Integral putStrLn ("We decided!") -- putStrLn ("We decided:\n" ++ show(1) ++ "!") -- ageJudge inpIntegral
You use the type class Integral, which contains Int and Integer, for ageJudge; it is better to use Double, as you use this type for reading the age. Another option is, to use the function "round" to round the age. Note, that you cannot use Integral as a type.
