The round() function in Python is used to round a decimal value to the nearest multiple of 10. You can also specify to what number of decimal places the function rounds. If the number is less than 5, the number next to it will be preserved, if it is greater than 5, the number next to it will be rounded up to 1 unit.

Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform related Python function queries.

In this context, we shall look into using the round() function in Python.

The round() function rounds to the decimal place you specify.

Basically, If the number is less than 5, the number next to it will be preserved, if it is greater than 5, the number next to it will be rounded up to 1 unit.

It's syntax is given below:

`round(number, digits)`

- number: number of decimals you want to round (Required).
- digits: the decimal place you want to round to. Default is 0 (Optional).

1. Take a look at the below function:

`x = round(3.475, 2)`

print(x)

It's output will give:

`3.48`

2. Basic round() function:

`print(round(13.4))`

print(round(12.6))

print(round(10.3))

It's Output will give:

`13`

10

3. Specify rounding position:

`x = round(13.4567, 2)`

y = round(12.23456, 3)

print(x)

print(y)

The Output will give:

`13.46`

12.235

4. Python round() up:

`print(round(11.6))`

print(round(14.7))

It's Output will give:

`12`

15

5. Python round() down:

`print(round(11.3))`

print(round(14.5))

It's Output will give:

`11`

14

This article covers how to use the round() function in Python. In fact, the round() function returns a floating-point number rounded to the specified number of decimals.

**round() Return Value**

The round() function returns the:

- nearest integer to the given number if ndigits is not provided.
- number rounded off to the ndigits digits if ndigits is provided.
