There's also n.ndigits(), which I think directly returns the number of digits without doing any conversion to a string. You can even specify different bases, so if n = 8, you get 1 for base 10, and 3 for base 2. You can also put in really large bases: sage: n = 1025 sage: n.ndigits(1024) 2 Dan -- --- Dan Drake ----- http://mathsci.kaist.ac.kr/~drake -------
