Replicating a Value to the Specified Length in R Programming - rep_len() Function

Rounding off a value to specific digits in R Programming - round() Function

Last Updated : 01 Jun, 2020

R Language provides an inbuilt function round() which rounds off to the given number of digits, if no number of digits is provided for round off, it rounds off the number to the nearest integer.

Syntax: round(x, digits=n) Parameter: x: Number to be rounded off digit: Specified digits

Example 1:

Python3

# R program to calculate round value 
  
# Using round() method 
answer1 <- round(2.356) 
answer2 <- round(2.356, digits = 2)  
answer3 <- round(2.5)
answer4 <- round(2.5, digits = 1)  

print(answer1) 
print(answer2) 
print(answer3) 
print(answer4)

Output:

Example 2:

Python3

# R program to calculate round value 
  
# Using round() method 
answer1 <- round(c(1.5, 2.6, -3, -3.4)) 

print(answer1)

Output:

2  3 -3 -3
