It turns out such an error when calculating the exponent if the input is given a value of 710 and higher. How can one calculate the exponent in this case, even with an error?

 >>> math.exp(710) Traceback (most recent call last): File "<input>", line 1, in <module> OverflowError: math range error

  • Sorry, this line is incomprehensible to me. Is it possible to get around this limitation? - Mavar
  • You can, neglecting accuracy - Igor Lavrynenko
  • Thank. How to do it, what will this function look like? math.exp(710) - Mavar

It is necessary to use a wider float type. For example, you can use the numpy package types.

 import numpy as np val = 711 print(np.exp(val, dtype=np.float128))

    @Mavar, if only to write the function of calculating the exponent. - mkkik
