python, multiply power of 10 in, strange number

Question

(Pdb) int(math.pow(10, num_digits))
100000000000000005366162204393472
(Pdb) num_digits
32

When num_digits are big numbers, something is messed up..

What is your Question? Can you provide some additional information on what you mean with "something is messed up"? — Markus Schmidgall, Oct 14 '22 at 08:43
`math.pow` works with floating point numbers, which have inaccuracies. I think `10**num_digits` would work with integers and would be precise — Alexey S. Larionov, Oct 14 '22 at 08:44

If you want pow with integers use **

n**32

math.pow uses a float

an explanation about the implementation can be found here : How did Python implement the built-in function pow()?
