Ruby CMath cbrt() Method with example
cbrt method is a Math class method in Ruby which is used to calculate the cube root of the given value.
Syntax: Math.cbrt(z)
Parameter: Here, z is the value whose cube root is to be calculated.
Returns: This method returns the cube root of the given number.
Below programs illustrate the use of above-discussed method:
Example 1:
# Ruby code for cbrt() method require 'cmath' # Initializing value a = 27 b = 5 . 45 # Printing result puts "Cube root value of a : #{CMath.cbrt(a)}\n\n" puts "cube root value of b : #{CMath.cbrt(b)}\n\n" |
Output:
Cube root value of a : 3.0 cube root value of b : 1.7598088635408027
Example 2:
# Ruby code for cbrt() method require 'cmath' # Initializing values a = 78 b = 729 # Printing result puts "Cube root value of a : #{CMath.cbrt(a)}\n\n" puts "cube root value of b : #{CMath.cbrt(b)}\n\n" |
Output:
Cube root value of a : 4.272658681697917 cube root value of b : 8.999999999999998
