Python: OverflowError: math range error

Question

I get a Overflow error when i try this calculation, but i cant figure out why.

1-math.exp(-4*1000000*-0.0641515994108)

Answer 1

I think the value gets too large to fit into a double in python which is why you get the OverflowError. The largest value I can compute the exp of on my machine in Python is just sligthly larger than 709.78271.
