Python pow() Function Example
The pow() in Python is simple to use, just pass two values as the parameters.
Python3
print ( pow ( 3 , 2 )) |
Output:
9
Power Function in Python with Modulus
We can pass more than two parameters to the pow() in Python. The first parameter is the number on which we want to apply the Pow() function, the second parameter is the power and the third parameter is to perform the modulus operation.
It return the value of 3 to the power of 4, modulus 10 (same as (3 * 3 * 3 * 3) % 10)
Python3
# Python code to demonstrate pow() print ( "The value of (3**4) % 10 is : " , end = "") # Returns 81%10 # Returns 1 print ( pow ( 3 , 4 , 10 )) |
Output:
The value of (3**4) % 10 is : 1
Implementation Cases in pow() Function in Python
The below table summarises the different cases to apply the Python pow() function.
Example:
Python code to discuss negative and non-negative cases.
Python3
# positive x, positive y (x**y) print ( "Positive x and positive y : " , end = "") print ( pow ( 4 , 3 )) print ( "Negative x and positive y : " , end = "") # negative x, positive y (-x**y) print ( pow ( - 4 , 3 )) print ( "Positive x and negative y : " , end = "") # positive x, negative y (x**-y) print ( pow ( 4 , - 3 )) print ( "Negative x and negative y : " , end = "") # negative x, negative y (-x**-y) print ( pow ( - 4 , - 3 )) |
Output:
Positive x and positive y : 64 Negative x and positive y : -64 Positive x and negative y : 0.015625 Negative x and negative y : -0.015625
Python pow() Function
Python pow() function returns the result of the first parameter raised to the power of the second parameter.
