Sean ------------------------------------------------------------------------ [2002-03-02 11:44:47] sama@inf.ufsc.br The function resource gmp_invert() doesn't work right. It always return zero. I implemented the extended Euclides algoritm that do exactly the same that this function and, it returned me the right value. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15835&edit=1
