Python math.fabs() – Absolute Value

Python math.fabs()

math.fabs(x) function returns the absolute value of x.

Syntax

The syntax to call fabs() function is

math.fabs(x)

where

Examples

1. Absolute value of an integer

In the following program, we find the absolute value of integer number in the variable x.

import math

x = -8
result = math.fabs(x)
print('fabs(x) :', result)

Output

fabs(x) : 8.0

2. Absolute value of a floating point number

In the following program, we find the absolute value of a floating point number -8.586.

import math

x = -8.586
result = math.fabs(x)
print('fabs(x) :', result)

Output

fabs(x) : 8.586

3. Absolute value of negative infinity

In the following program, we find the absolute value of negative infinity.

import math

x = -math.inf
result = math.fabs(x)
print('fabs(x) :', result)

Output

fabs(x) : inf
