Hi,
Im not sure if this is more of a math question or a python question.
I have a variable in python:
>>> v = 10.0**n
is there a way to find the value of n if i know only v aside from
str(v).split('+')[1] ? that seems like too much of a hack and I was
wondering if there was a faster way of doing it?
Thanks for any pointers
Astan
the "reverse" of a power to is logarithm
so v = 10**n <=> math.log(v,10) = n
