Python abs() usage and example

Python built-in functions

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

The syntax of the abs() method is:

abs(num)

abs() parameter

The abs() method takes one parameter:

• num-The number to return its absolute value. The number can be:

1. Integer

2. Floating-point number

3. Complex number

From the value returned by abs()

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

• For integers-Return the absolute value of an integer

• For floating-point numbers-Return the absolute value of a floating-point number

• For complex numbers-Return the size of the number

Example1: Get the absolute value of a number

# Random integer
integer =　-20
print('-2The absolute value of 0 is: 'abs(integer))
# Random floating-point number
floating =　-30.33
print('-30.33The absolute value is: 'abs(floating))

When running the program, the output is:

-2The absolute value of 0 is:　20
-30.33The absolute value is:　30.33

Example2: Get the magnitude of a complex number

# Random complex number
complex = (3　-　4j)
print('3　-　4The size of j is: 'abs(complex))

When running the program, the output is:

3　-　4The size of j is:　5.0
