OverflowError：（34，“结果太大”）计算e ^-（b * dE）

Question

I want to calculate boltzmann distribution which is e**-(b*dE) . b is 1/kT where k is boltzmann constant and T is temperature. dE is delta energy.

I use from scipy.constants import k to get the value of k and import math to get the value of e . dE and T are integer.

Is there any library that can import to get the value of e^-(b*dE) easily?

Answer 1

You should not use the ^ (xor) operator, but ** (pow):

e**-(b*dE)

Or:

import math
math.exp(-(b*dE))
