Library Coq.ZArith.ZOrderedType
DecidableType structure for binary integers
Note that the last module fulfills by subtyping many other
interfaces, such as DecidableType or EqualityType.
OrderedType structure for binary integers
Note that Z_as_OT can also be seen as a UsualOrderedType
and a OrderedType (and also as a DecidableType).
An order tactic for integers
Note that z_order is domain-agnostic: it will not prove
1<=2 or x<=x+x, but rather things like x<=y -> y<=x -> x=y.
