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
