# Python | math.fabs() function

• Last Updated : 11 Mar, 2019

In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. `math.fabs()` function returns the absolute value of the number.

```Syntax: math.fabs(x)

Parameter:
x: This is a numeric expression.

Returns: the absolute value of the number.```

Code #1:

 `# Python code to demonstrate the working of fabs()``   ` `# importing "math" for mathematical operations ``import` `math ``   ` `x ``=` `-``33.7``   ` `# returning the fabs of 33.7``print` `(``"The fabs of 33.7 is : "``, end ``=``"") ``print` `(math.fabs(x))`

Output:

```The fabs of 33.7 is : 33.7
```

Code #2:

 `# Python code to demonstrate the working of fabs()``   ` `# importing "math" for mathematical operations ``import` `math ``   ` `# prints the fabs using fabs() method ``print` `(``"math.fabs(-13.1) : "``, math.fabs(``-``13.1``))``print` `(``"math.fabs(101.96) : "``, math.fabs(``101.96``))`

Output:

```math.fabs(-13.1) :  13.1
math.fabs(101.96) :  101.96
```
