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

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.
