How about:
py> def digits(f):
... return len(str(f).split('.')[1].rstrip('0'))
...
py> for f in [0.103, 0.1030, 0.0103, 0.010300]:
... print f, digits(f)
...
0.103 3
0.103 3
0.0103 4
0.0103 4
I believe the rstrip is unnecessary because I think str() will never
produce additional following zeros, but you can guarantee it by calling
rstrip if you want.
Note that, for example, 0.103 and 0.1030 are identical as far as Python
is concerned, so I hope you're not hoping to show a difference between
these two...
