How does python calculate the integer power of a value

Today, I would like to share with you the relevant knowledge of how python calculates the integer power of numerical values. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

The problem of integer power of numerical value

Given a floating-point number of type double base and an integer exponent of type int. Find the exponent power of base. Make sure that base and exponent are not 0 at the same time
