I don't find any sign(x) function in the math library (return the sign of the value). I've read that math module is a wrapper to C math lib and that C math lib has not sign(), so...
I've implement my own sign function of course (it's easy) but a standard one in math would be better and could be faster. How do you implement this or is there any other module with a sign() function ? -- Pierre-Alain Dorange <http://microwar.sourceforge.net/> Ce message est sous licence Creative Commons "by-nc-sa-2.0" <http://creativecommons.org/licenses/by-nc-sa/2.0/fr/> -- http://mail.python.org/mailman/listinfo/python-list
