# StrictMath cbrt() Method in Java

• Last Updated : 13 Dec, 2021

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
