I don't think that's what you really want to do.
What you really want is for dx to be a float rather than being truncated to
an integer. Division is going to behave that way in the future, so if you
want it to behave that way now, you can write
from __future__ import division
at the beginning of your program.
If for some reason you don't want to rely on using a version of Python that
knows about this future behavior, you might consider
dx = float(abs(i2 - i1))/min(i2, i1)
as an alternative.
