... and you're restricting to the positive integers, I take it?
I still have rounding problems:
>>> def l(x):
... return math.floor(math.log(x, 10)) + 1
...
>>> l(10)
2.0
>>> l(100)
3.0
>>> l(1000)
3.0
>>> l(10000)
5.0
>>> l(100000)
6.0
>>> l(1000000)
6.0
>>> l(10000000)
8.0
While modest mollification improves these results, it's going
to be tough to beat len(str(x)).
