Why am I getting a parse error on "a b c d"?
computeNumbers :: Float -> Int -> Int -> Float -> Float
computerNumbers (a b c d) = ((pi * a/2 ^2) * 0.002 + (((pi * a/2 ^2) * 0.001) * b) + c * 0.55) * 1.5 + (if d > 0 then d * 0.9 else d)
I have tried everything from deleting every space between words to make sure that I did not use TAB by mistake and rearrange the brackets. Nothing worked so far.
>Solution :
Get rid of the parentheses entirely.
Without the parens you are binding the names to the four arguments. With the parens you are matching a single argument with a pattern that does not match a Float.
