The java.lang.StrictMath.cbrt() is an inbuilt method in Java which is used to return the cube root of a given double value. The method shows three special results: 

  • The result is a zero with the same sign as the argument when the given argument is zero.
  • The result is infinity with the same sign of argument when the argument is infinite.
  • The result is NaN when the given argument is NaN.


Syntax:  

public static double cbrt(double num)


Parameters: This method accepts one parameter num which is of double type whose cube root is required to be found.
Return Value : The method returns the cube root of num.
Below programs illustrate the java.lang.StrictMath.cbrt() method: 
Program 1:  

java 
// Java program to illustrate the
// java.lang.StrictMath.cbrt()
import java.lang.*;

public class Geeks {

    public static void main(String[] args)
    {

        double val1 = 8.05, val2 = 27, val3 = 0;

        // It returns the cube root of a double value
        double cbrtvalue = StrictMath.cbrt(val1);
        System.out.println("Cube root of "+val1+
                                  " = " + cbrtvalue);

        cbrtvalue = StrictMath.cbrt(val2);
        System.out.println("Cube root of "+val2+
                                  " = " + cbrtvalue);


        cbrtvalue = StrictMath.cbrt(val3);
        System.out.println("Cube root of "+val3+
                                  " = " + cbrtvalue);

    }
}

Output: 
Cube root of 8.05 = 2.0041580161269152
Cube root of 27.0 = 3.0
Cube root of 0.0 = 0.0

 

Program 2: 

java 
// Java program to illustrate the
// java.lang.StrictMath.cbrt()
import java.lang.*;

public class Geeks {

    public static void main(String[] args)
    {

        double val1 = -8.05, val2 = 128, val3 = 0;

        // It returns the cube root of a double value
        double cbrtvalue = StrictMath.cbrt(val1);
        System.out.println("Cube root of "+val1+
                                  " = " + cbrtvalue);

        cbrtvalue = StrictMath.cbrt(val2);
        System.out.println("Cube root of "+val2+
                                  " = " + cbrtvalue);

        cbrtvalue = StrictMath.cbrt(val3);
         System.out.println("Cube root of "+val3+
                                  " = " + cbrtvalue);

    }
}

Output: 
Cube root of -8.05 = -2.0041580161269152
Cube root of 128.0 = 5.039684199579493
Cube root of 0.0 = 0.0
