Java Math cbrt() usage and example

Java Math Mathematical Methods

The Java Math cbrt() method returns the cube root of the specified number.

The syntax of the cbrt() method is:

Math.cbrt(double num)

Note: cbrt() is a static method. Therefore, we can use the class name to access the Math method.

cbrt() parameter

• num - The number to calculate the cube root of

cbrt() return value

• Returns the cube root of the specified number

• If the specified value is NaN, then return NaN

• If the specified number is 0, then return 0

Note: If the parameter is a negative number-num, then cbrt(-num) = -cbrt(num).

Example: Java Math cbrt()

class Main {
　　public static void main(String[] args) {
　　　　//　Create a double variable
　　　　double value1　= Double.POSITIVE_INFINITY;
　　　　double value2　=　27.0;
　　　　double value3　=　-64;
　　　　double value4　= 0.0;
　　　　//　cubic root of infinity
　　　　System.out.println(Math.cbrt(value1));　　//　Infinity
　　　　//　cubic root of a positive number
　　　　System.out.println(Math.cbrt(value2));　　//　3.0
　　　　//　cubic root of a negative number
　　　　System.out.println(Math.cbrt(value3));　　//　-4.0
　　　　//　cubic root of zero
　　　　System.out.println(Math.cbrt(value4));　　//　0.0
　　}
}

In the above example, we used the Math.cbrt() method to calculateInfinity,Positive Numbers,Negative NumbersAndZerocubic root.

Here, Double.POSITIVE_INFINITY is used to implement positive infinity in the program.

When we pass an int value to the cbrt() method, it automatically converts the int value to the double value.

int a =　125;
Math.cbrt(a);　　　//　Return　5.0
