type Poly = [Float]
addPoly::Poly->Poly->Poly
addPoly x y = zipWith (+) x y instance (Float a) => Num (Poly a)
where
(+) = addPoly I got the error message "Cannot use type synonym
in instance head" when I was trying to compile the codes above. Can anyone tell
me why and how to solve it?
Cheers
Benny
