# 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 offdigits: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.
