Ruby | Integer sqrt() function
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:
5
4
10
2
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:
8
