# Python math.fabs() – Absolute Value

Contents

## 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.

Python Program

``````import math

x = -8
result = math.fabs(x)
print('fabs(x) :', result)``````
Run Code Copy

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.

Python Program

``````import math

x = -8.586
result = math.fabs(x)
print('fabs(x) :', result)``````
Run Code Copy

Output

``fabs(x) : 8.586``

### 3. Absolute value of negative infinity

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

Python Program

``````import math

x = -math.inf
result = math.fabs(x)
print('fabs(x) :', result)``````
Run Code Copy

Output

``fabs(x) : inf``
