synopsis: "A definition of rational numbers"
description: """
Definition of integers as the usual symetric
completion of a semi-group and of rational numbers as the product of
integers and strictly positive integers quotiented by the usual relation.
This implementation assumes two sets of axioms allowing to define
quotient types and subset types. These sets of axioms should be
proved coherent by mixing up the deliverable model and the setoid model
(both are presented in Martin Hofmann' thesis)."""

trueDry install with the current Coq version:
opam install -y --show-action coq-rational.8.5.0 coq.8.4.5[NOTE] Package coq is already installed (current version is 8.4.5).
The following dependencies couldn't be met:
- coq-rational -> coq >= 8.5 -> ocaml >= 4.05.0
base of this switch (use `--unlock-base' to force)
- coq-rational -> coq >= 8.5 -> coq-core -> ocaml >= 4.09.0
base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
- No available version of coq satisfies the constraints
No solution found, exiting
Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:
opam remove -y coq; opam install -y --show-action --unlock-base coq-rational.8.5.0truetrueNo files were installed.
