[Python] Numpy power function returns incorrect value 0

Question

I am trying the following power operation, but I get the wrong answer. How can I fix it?

>>> np.power(100,50)

0

Answer 1

By default, the power() function uses 64-bit integer dtype. It is too small for such a big number. You need to use float64 dtype that offers a larger but inexact, range of possible values.

Here is the fix:

>>> np.power(100,50, dtype=np.float64)
1e+100
