# Rounding off values in R Language – round() Function

• Last Updated : 15 Apr, 2021

round() function in R Language is used to round off values to a specific number of decimal value.

Syntax: round(x, digits)
Parameters:
x: Value to be round off
digits: Number of digits to which value has to be round off

Example 1: Rounding off the values

## Python3

 `# R program to illustrate``# round function` `# Create example values``x1 <``-` `1.2`                          `x2 <``-` `1.8``x3 <``-` `-` `1.3``x4 <``-` `1.7` `# Apply round function``round``(x1)                          ``round``(x2)``round``(x3)``round``(x4)` `print``(x1, x2, x3, x4)`

Output :

``` 1
2
-1
2```

Here in the above code, we have round off the values with 4 data x1, x2, x3, and x4 using the function round(), and printed the new values.
Example 2: Rounding off to certain digits

## Python3

 `# R program to illustrate``# round to a certain digit` `# Create numeric with many digits``x2 <``-` `3.14734343243`   `# Round to three decimal places                 ``round``(x2, digits ``=` `3``) ` `print``(x2)            `

Output:

` 3.147 `

Here in the above code, the value of a numeric vector is round off till 3 digits.
