# Python3.x Python3 fabs() Function

## Description
The fabs() method returns the absolute value of a number as a floating-point number, e.g., math.fabs(-10) returns 10.0.
The fabs() function is similar to the abs() function, but it has two differences:
* abs() is a built-in function. The fabs() function is defined in the math module.
* The fabs() function is only effective for floating-point and integer values. abs() can also be used with complex numbers.
* * *
## Syntax
Here is the syntax for the fabs() method:
import math math.fabs( x )
**Note:** fabs() cannot be accessed directly; you need to import the math module and call the method via a static object.
* * *
## Parameters
* x -- A numeric expression, which can be an integer, float, etc. The function returns the absolute value of x, i.e., a non-negative number.
* * *
## Return Value
Returns the absolute value of the number.

## Examples
The following examples demonstrate the use of the fabs() method:
## Example 1
import math
x = -1.5
y =math.fabs(x)
print(y)# Output 1.5
x =10
y =math.fabs(x)
print(y)# Output 10.0
In the above example, fabs(-1.5) returns the absolute value of -1.5, which is 1.5, and fabs(10) returns the absolute value of 10, which is 10.0. Note that the return value is always a floating-point number, even if the input parameter is an integer.
The output of the above example is:
1.510.0
## Example 2
#!/usr/bin/python3
import math# Import the math module
print("math.fabs(-45.17) : ",math.fabs(-45.17))
print("math.fabs(100.12) : ",math.fabs(100.12))
print("math.fabs(100.72) : ",math.fabs(100.72))
print("math.fabs(math.pi) : ",math.fabs(math.pi))
The output of the above example is:
math.fabs(-45.17) : 45.17 math.fabs(100.12) : 100.12 math.fabs(100.72) : 100.72 math.fabs(math.pi) : 3.141592653589793
