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)."""

Dry install ๐Ÿœ๏ธ

Dry install with the current Coq version:

Command
opam install -y --show-action coq-rational.8.6.0 coq.8.12.0
Return code
5120
Output
[NOTE] Package coq is already installed (current version is 8.12.0).
The following dependencies couldn't be met:
  - coq-rational -> coq < 8.7~ -> ocaml < 4.06.0
      base of this switch (use `--unlock-base' to force)
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-rational.8.6.0
