Python – 0**0 == 1?
Question:
I was playing around with ** operator, and noticed that:
0**0 == 1
And
pow(0, 0) == 1
And even math:
math.pow(0, 0) == 1
And Google! (search for 0**0)
Why is it so? As far as I know 0**0 is undefined
Answers:
No, you are mistaken. It works as it should.
n/0 is undefined. 0**0 however is 1 because any number raised to the power of 0 is 1.
Here are some references:
https://en.wikipedia.org/wiki/Exponentiation#Zero_to_the_power_of_zero
Anything to the power 0, by definition, is 1.
Because of the math rules. Everything in a 0-th power is 1.
