Ruby | Integer sqrt() function

Last Updated : 07 Jan, 2020

The sqrt() function in Ruby returns the integer square root of the non-negative integer n, i.e. the largest non-negative integer less than or equal to the square root of n

Syntax: Integer.sqrt(number)

Parameter: The function takes the integer whose square root is to be returned. It throws an error “out of domain” if a negative number is passed.

Return Value: The function returns the integer square root.

Example 1:

#Ruby program for sqrt() function 
  
#Initializing the number 
num1 = 25 num2 = 16 num3 = 100 num4 = 5 
  
#Prints the sqrt of a number 
                                      puts Integer.sqrt(num1) 
                                          puts Integer.sqrt(num2) 
                                              puts Integer.sqrt(num3) 
                                                  puts Integer.sqrt(num4) 

Output:

Example 2:

#Ruby program for sqrt() function 
  
#Initializing the number 
num1 = 64 num2 = 81 num3 = 49 num4 = 36 
  
#Prints the sqrt of a number 
                                     puts Integer.sqrt(num1) 
                                         puts Integer.sqrt(num2) 
                                             puts Integer.sqrt(num3) 
                                                 puts Integer.sqrt(num4) 

Output:
