Hi

Just think what is the type of your function?
shape -> int or shape -> float ????

Regards,
Alex

Could you please tell me why the following doesn't work?

type shape = Square of int * int * int
        |Circle of float * float * float;;
let area s =
  match s with
    Square (_, _, d) -> d * d
   |Circle (_, _, r) -> 3.14 *. r *. r;;

Regards,
Ye
