val compare : t -> t -> int
val to_string : t -> string
val sum : t -> t -> t

An associative and commutative binary operation over the type t. The following should hold:

  • sum a (sum b c) = sum (sum a b) c.
  • sum a b = sum b a.
val prod : t -> t -> t

An associative binary operation over the type t. The following should hold:

  • prod a (prod b c) = prod (prod a b) c.
  • prod a (sum b c) = sum (prod a b) (prod a c).
val one : t

The identity for the prod operation. The following should hold:

  • prod one t = t.
  • prod t one = t.

As an example, if t where the type bool and prod and sum were && and ||, respectively, then one should be the value true.

val zero : t

The identity for the sum operation. The following should hold:

  • sum zero t = t.
  • sum t zero = t.
  • prod zero t = zero.
  • prod t zero = zero.

As an example, if t where the type bool and prod and sum were && and ||, respectively, then zero should be the value false.
