Module type Ring.T

Module type arithmetic types equipped with addition and multiplication.

type t
val add : t -> t -> t
val mul : t -> t -> t

* div p1 p2 returns the division of p1 by p2. * None if the division is not exact

val neg : t -> t
val to_int : t -> int option

None if the value cannot be converted exactly to an integer
