---

Syntax

The syntax to call fabs() function is

math.fabs(x)

where

Parameter	Required	Description
x	Yes	A numeric value.

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)

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)

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)

Output
