# Python | math.floor() 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.floor()` function returns the largest integer not greater than x. If number is already integer, same number is returned.

```Syntax: math.floor(x)

Parameter:
x: This is a numeric expression.

Returns:  largest integer not greater than x.```

Code #1:

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

Output:

```The floor of 33.7 is : 33
```

Code #2:

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

Output:

```math.floor(-13.1) :  -14
math.floor(101.96) :  101
```
