Python is an interpreted, high-level language that is often used for data science, machine learning and scientific computing. Python has a wide range of built-in math functions that can be used to perform various mathematical operations. One such function is math.rint. The math.rint function is used to round a given number to its nearest integer. In this article, we will discuss the syntax and usage of the math.rint function and its parameters in Python.

## What is math.rint(3.6)?

The math.rint(x) function takes a single number as its parameter and rounds it to its nearest integer. For example, math.rint(3.6) will return a result of 4, because 4 is the closest integer to 3.6.

### Syntax

The syntax of the math.rint function is as follows:

```
math.rint(x)
```

Here, x is the number that needs to be rounded to the nearest integer.

### Parameters

*x*: This is the single number that needs to be rounded to the nearest integer.

### Return Value

The math.rint function returns an integer value which is the nearest integer to the given number, x.

## Examples

Let’s understand the math.rint function with some examples.

Example 1: Round a Given Number to the Nearest Integer

```
# Python program to demonstrate math.rint()
# import math module
import math
# use of math.rint()
# a number which needs to be rounded
x = 8.3
# calculus
y = math.rint(x)
# printing the value of y
print("value of y = ", y)
```

This code will return the following output:

```
value of y = 8
```

Example 2: Round a Large Decimal Number to the Nearest Integer

```
# Python program to demonstrate math.rint()
# import math module
import math
# use of math.rint()
# a number which needs to be rounded
x = 136.85831
# calculus
y = math.rint(x)
# printing the value of y
print("value of y = ", y)
```

This code will return the following output:

```
value of y = 137
```
