Python abs() Function

The python abs() function is used to return absolute value of a number. It takes only one argument, a number whose absolute value is to be returned. The argument can be an integer and floating point number. If the argument is a complex number, then, abs() returns its magnitude.

Signature

• abs (num)

Parameters

• num - A number whose absolute value is to be returned. The number can be:

1. integer
2. floating number
3. complex number

Return

It returns the absolute value of the specified number.

Python abs() Function Example 1

Let's see an example to get absolute value of a number.

1. #  integer number  
2. integer = -40  
3. print('Absolute value of -40 is:', abs(integer))  
4.   
5. #  floating number  
6. floating = -40.83  
7. print('Absolute value of -40.83 is:', abs(floating))  

Output:

Absolute value of -40 is: 40
Absolute value of -40.83 is: 40.83

Python abs() Function Example 2

This example shows magnitude of a complex number.

1. #complex number  
2. complex = (3 - 4j)  
3. print('Magnitude of 3 - 4j is:', abs(complex))  

Output:

Magnitude of 3 - 4j is: 5.0
