Python float() giving incorrect values

Question

When I enter float(1)/(2^7) in the Python console it outputs 0.2. But it is actually 0.0078125.

Could anyone please tell what I am doing wrong?

`^` is the XOR operator. If you want to raise 2 to the power of 7, you must use `2 ** 7`. — vaultah, Apr 27 '16 at 16:21

You probably want to use the ** operator instead of ^. ** is the power operator in python, ^ is the Binary XOR operator.

float(1)/(2**7) yields the correct 0.0078125.
