Python abs() Builtin Function

Python abs() function takes number as argument and returns the absolute value of given number.

In this tutorial, we will pass integer, floating point number or complex numbers as argument to abs() function, and observe the return value.

Syntax

The syntax to find the absolute value of a number is

result = abs(number)

The number could be integer, floating point number, complex number, or any object that implements __abs__() function.

Absolute Value of Integer

Pass an integer to abs() function, and it shall return its absolute value.

In the following example, we will call abs() function and pass a positive integer and negative integer to it.

Python Program

#positive integer
i = 14
result = abs(i)
print(f'abs({i}) is {result}')

#negative integer
i = -14
result = abs(i)
print(f'abs({i}) is {result}')
Try Online

Output

abs(14) is 14
abs(-14) is 14

Absolute Value of Floating Point Number

Pass a floating point number to abs() function, and it shall return its absolute value.

In the following example, we will call abs() function and pass a float value and negative float value to it.

Python Program

#positive floating point number
f = 14.52
result = abs(f)
print(f'abs({f}) is {result}')

#negative floating point number
f = -14.52
result = abs(f)
print(f'abs({f}) is {result}')
Try Online

Output

abs(14.52) is 14.52
abs(-14.52) is 14.52

Absolute Value of Complex Number

Pass a complex number to abs() function, and it shall return the magnitude of given complex number.

In the following example, we will call abs() function and pass complex number to it.

Python Program

#complex number with positive real and imaginary parts
c = 3 + 4j
result = abs(c)
print(f'abs({c}) is {result}')

#complex number with negative real and imaginary parts
c = -3-4j
result = abs(c)
print(f'abs({c}) is {result}')
Try Online

Output

abs((3+4j)) is 5.0
abs((-3-4j)) is 5.0
