Binary operations

val compare : t -> t -> int
val str : IStdlib.Pp.env -> t -> string
val equal : t -> t -> bool
val injective : t -> bool

This function returns true if the operation is injective wrt. each argument: op(e,-) and op(-, e) is injective for all e. The return value false means "don't know".

val is_zero_runit : t -> bool

This function returns true if 0 is the right unit of binop. The return value false means "don't know".

val symmetric : t -> t option

symmetric bop returns' Some bop' if x bop y if and only if y bop' x for all x, y, or None if no such bop' exists

val negate : t -> t option

negate bop returns' Some bop' if not (x bop y) if and only if x bop' y for all x, y, or None if no such bop' exists
