The first one is the intended one; the two others are side-effects.\r\n\r\n- Parsing and printing of real literals no longer use the binary representation; they now use `IZR`. In other words, `5%R` is no longer syntactically equal to `1 + 2 * 2`; it is now `IZR 5`.\r\n\r\n- `IZR` no longer reduces to a unary representation but to a binary representation, that is, `IZR 5` is no longer `2 + 1 + 1 + 1` but `1 + 2 * 2`. (This also means that `5%R` is still convertible to `1 + 2 * 2`, due to the first item.)\r\n\r\n- Morphism rings no longer unfold their ring morphisms. This is mostly a hack so that `ring_simplify` and `field_simplify` are still usable on `R`.\r\n\r\nNote that several of these commits (8d92932, e0a09d3, 3758cbf, 7f82a39, e3c978c) are worth applying even if this feature is deemed too intrusive."},"comment":{"url":"https://api.github.com/repos/coq/coq/issues/comments/277073022","html_url":"https://github.com/coq/coq/pull/415#issuecomment-277073022","issue_url":"https://api.github.com/repos/coq/coq/issues/415","id":277073022,"user":{"login":"herbelin","id":460771,"avatar_url":"https://avatars.githubusercontent.com/u/460771?v=3","gravatar_id":"","url":"https://api.github.com/users/herbelin","html_url":"https://github.com/herbelin","followers_url":"https://api.github.com/users/herbelin/followers","following_url":"https://api.github.com/users/herbelin/following{/other_user}","gists_url":"https://api.github.com/users/herbelin/gists{/gist_id}","starred_url":"https://api.github.com/users/herbelin/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/herbelin/subscriptions","organizations_url":"https://api.github.com/users/herbelin/orgs","repos_url":"https://api.github.com/users/herbelin/repos","events_url":"https://api.github.com/users/herbelin/events{/privacy}","received_events_url":"https://api.github.com/users/herbelin/received_events","type":"User","site_admin":false},"created_at":"2017-02-02T20:26:13Z","updated_at":"2017-02-02T20:26:13Z","body":"Don't feel expert enough to comment in the details but I like it."}}
