* Remove fourier pluginGravatar Maxime Dénès2018-07-17

* Change the parser and printer so that they use IZR for real constants.Gravatar Guillaume Melquiond2017-03-22
| | | | | | | | | | | | | | | | | | | | | | There are two main issues. First, (-cst)%R is no longer syntactically equal to (-(cst))%R (though they are still convertible). This breaks some rewriting rules. Second, the ring/field_simplify tactics did not know how to refold real constants. This defect is no longer hidden by the pretty-printer, which makes these tactics almost unusable on goals containing large constants. This commit also modifies the ring/field tactics so that real constant reification is now constant time rather than linear. Note that there is now a bit of code duplication between z_syntax and r_syntax. This should be fixed once plugin interdependencies are supported. Ideally the r_syntax plugin should just disappear by declaring IZR as a coercion. Unfortunately the coercion mechanism is not powerful enough yet, be it for parsing (need the ability for a scope to delegate constant parsing to another scope) or printing (too many visible coercions left).

| | | | | | | Most of these heavyweight annotations were introduced a long time ago by the automatic 7.x -> 8.0 translator git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15518 85f007b7-540e-0410-9357-904b9bb8a0f7

* Remove the svn-specific $Id$ annotationsGravatar letouzey2010-04-29
| | | | | | | | | | | - Many of them were broken, some of them after Pierre B's rework of mli for ocamldoc, but not only (many bad annotation, many files with no svn property about Id, etc) - Useless for those of us that work with git-svn (and a fortiori in a forthcoming git-only setting) - Even in svn, they seem to be of little interest git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12972 85f007b7-540e-0410-9357-904b9bb8a0f7
* Added alternate versions of existing lemmas on sqrt.Gravatar gmelquio2009-11-02
| | | | | | | | | | | | | | | | Indeed, since sqrt is a total function, most lemmas are true, even for negative inputs. For instance, sqrt_le_1 was 0 <= x -> 0 <= y -> x <= y -> sqrt x <= sqrt y while sqrt_le_1_alt is just x <= y -> sqrt x <= sqrt y. Naming is done by adding _alt suffixes. In an ideal world (Coq 9.0?), these new lemmas should just replace the original ones. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12457 85f007b7-540e-0410-9357-904b9bb8a0f7

* Une passe sur les réels:Gravatar herbelin2008-03-23
| | | | | | | | | | | | | | | | | | | | | | | | - Renommage de Rlt_not_le de Fourier_util en Rlt_not_le_frac_opp pour éviter la confusion avec le Rlt_not_le de RIneq. - Quelques variantes de lemmes en plus dans RIneq. - Déplacement des énoncés de sigT dans sig (y compris la complétude) et utilisation de la notation { l:R | }. - Suppression hypothèse inutile de ln_exists1. - Ajout notation ² pour Rsqr. Au passage: - Déplacement de dec_inh_nat_subset_has_unique_least_element de ChoiceFacts vers Wf_nat. - Correction de l'espace en trop dans les notations de Specif.v liées à "&". - MAJ fichier CHANGES Note: il reste un axiome dans Ranalysis (raison technique: Ltac ne sait pas manipuler un terme ouvert) et dans Rtrigo.v ("sin PI/2 = 1" non prouvé). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10710 85f007b7-540e-0410-9357-904b9bb8a0f7
