Ruby | Vector round() function

Last Updated : 07 Jan, 2020

The round() is an inbuilt method in Ruby returns a new vector with entries rounded to the given precision

Syntax: vec1.round()

Parameters: The function accepts a single parameter

Return Value: It returns a new vector with entries rounded to the given precision

Example 1:

# Ruby program for round() method in Vector 
     
# Include matrix  
require "matrix"
     
# Initialize the vector 
vec1 = Vector[1.145332, 2.932423, 3.1332445] 
    
# Prints vector rounded to given precision 
puts vec1.round(3) 

Output:

Vector[1.145, 2.932, 3.133]

Example 2:

# Ruby program for round() method in Vector 
     
# Include matrix  
require "matrix"
     
# Initialize the vector 
vec1 = Vector[1.145332, 2.932423, 3.1332445] 
    
# Prints vector rounded to given precision 
puts vec1.round(0) 

Output:

Vector[1, 3, 3]
