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

`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

 `# R program to illustrate ` `# round functiom ` ` `  `# 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

 `# 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.
