Ruby CMath sqrt() Method with example

  • Last Updated : 07 Jan, 2020

sqrt method is a Math class method in Ruby which is used to calculate the square root of the given value.

Syntax: Math.sqrt(z)

Parameter: Here, z is the value whose square root is to be calculated.

Returns: This method returns the square root of the given number.

Below programs illustrate the use of above-discussed method:



Example 1:




# Ruby code for sqrt() method
require 'cmath'
  
# Initialize values 
a = 9
b = 78.15
  
# Printing result  
puts "Square root value of a : #{CMath.sqrt(a)}\n\n"  
puts "Square root value of b : #{CMath.sqrt(b)}\n\n"

Output:

Square root value of a : 3.0

Square root value of b : 8.84024886527523

Example 2:




# Ruby code for sqrt() method
require 'cmath'
  
# Initializing value 
a = 7841
b = 1234
  
# Printing result  
puts "Sqrt root value of a : #{CMath.sqrt(a)}\n\n"  
puts "Sqrt root value of b : #{CMath.sqrt(b)}\n\n"

Output:

Sqrt root value of a : 88.54942122905152

Sqrt root value of b : 35.12833614050059
