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