Python abs()

The abs() method returns the absolute value of the given number. If the number is a complex number, abs() returns its magnitude.

The syntax of abs() method is:

abs(num)

abs() Parameters

The abs() method takes a single argument:

  • num - number whose absolute value is to be returned. The number can be:
    1. integer
    2. floating number
    3. complex number

Return value from abs()

The abs() method returns the absolute value of the given number.

  • For integers - integer absolute value is returned
  • For floating numbers - floating absolute value is returned
  • For complex numbers - magnitude of the number is returned

Example 1: Get absolute value of a number

# random integer
integer = -20
print('Absolute value of -20 is:', abs(integer))

#random floating number
floating = -30.33
print('Absolute value of -30.33 is:', abs(floating))

When you run the program, the output will be:

Absolute value of -20 is: 20
Absolute value of -30.33 is: 30.33

Example 2: Get magnitude of a complex number

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

When you run the program, the output will be:

Magnitude of 3 - 4j is: 5.0
