math.lib pour c++ builder

**rimfoufa** · 01/03/2012, 12h11

bonjour;

Je veux télécharger math.lib pour c++ builder.

J'ai cherché beaucoup mais je trouve rien.

merci.

**totoche76** · 01/03/2012, 13h32

Hello,

Et pourquoi veux-tu télécharger math.lib ??
C'est inclus en standard avec Builder....

**rimfoufa** · 02/03/2012, 11h02

le prof m'a dit il faut télécharger cet bibliothèque

Je ne sais pas si elles existent d'une façon standard

**Mercusyo** · 02/03/2012, 11h37

Oui, la bibliothèque "math.lib" est dans le standard.

Problème peut être de compréhension avec ton professeur, non ?

Si tu fais #include <math.h> et que tu positionnes ton curseur dessus, ensuite clic droit et "ouvrir le fichier au niveau du curseur", est-ce que le fichier header de math s'ouvre ?

**rimfoufa** · 04/03/2012, 20h36

salut;

il me donne sce fichier:

math.h

le fichier math.h du C\C++ n'a pas besoin de math.lib !
Personnellement en C++Builder 6 (la version de 2002 comme ce fichier ci-dessus) ne contient pas de math.lib !
J'ai testé ce matin, j'ai inclu ce fichier, sans rien modifier aux options d'un projet, cela compile !
Ton installation de C++Builder 6 a du mal se passer !

Essaye plutôt "Math.hpp" c'est la bibliothèque de C++Builder issu du Delphi, au moins là le fichier compilé est fourni

Salut
Dans C++ Builder tu trouve également dans Source\math
les sources complet en c ou en asm de toutes les fonctions comprises dans cette bibliotèque C/C++ Run Time Library
cdlt

math.lib pour c++ builder
