proposition: Lemma isdeceq_NonnegativeRationals : ∏ x y : NonnegativeRationals, (x = y) ⨿ (x != y).
proof: Proof. intros x y. generalize (isdeceqhq (pr1 x) (pr1 y)) ; apply sumofmaps ; intros H. - left. apply subtypePath_prop. exact H. - right. intros H0 ; apply H. revert H0. apply base_paths. Qed.
