but when x = -20 it returns this error return math.pow(x, 1.0/3.0) ValueError: math domain error but why is that? is it impossible to calculate -20 ^ (1/3) ? here on my calculator i get the result -6,666666667, but python seens to dont now the answer, why? am i doing something wrong? =/ thanks to everyone who tries do help best regards katcipis _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
