In Ruby, you can use the Math module's sqrt method to find the square root of a number. Here's an example:
# Assignment of a number for which the square root is to be calculated
number = 16
# Using the sqrt method of the Math module to get the square root
square_root = Math.sqrt(number)
# Displaying the output
puts "The square root of #{number} is #{square_root}"
Output:
The square root of 16 is 4.0
You can also find the square root of a number using the exponentiation operator, as follows:
# Assigment of number for which square root is to be calculated
number = 25
# Using exponentiation operator to get the square root
square_root = number ** 0.5
# Displaying the output
puts "The square root of #{number} is #{square_root}"
Output:
The square root of 25 is 5.0
