Java cbrt Function

by

The Java cbrt Function is one of the Java Math Library function and it is used to find the cube root of a specified expression or an individual double value. In this article we will show you, How to write Math.cbrt function in Java Programming language with example.

Java cbrt Function syntax

The basic syntax of the Math.cbrt in Java Programming language is as shown below. Following function will accept positive double value as argument and returns the cube root of the specified expression or Value.

static double cbrt(double number); //Return Type is Double

// In order to use in program: 
Math.cbrt(double number);

Number: It can be a double value or a valid numerical expression for which you want to find the cube root.

  • If the number argument is positive or negative double value, Math.cbrt function will return the cube root of a given value.
  • If the number argument is not a number (NaN), java Math.cbrt function will return NaN.
  • If the number argument is infinity, Math.cbrt function will return the result as Infinity with same sign.

Java cbrt Function Example

The Java Math.cbrt Function allows you to find the cube root of a specified expression or an individual double value. In this Java program, We are going to find the same and display the output.

JAVA CODE

// Java Math.cbrt Function
package MathFunctions;

public class CbrtMethod {
	public static void main(String[] args) {
		double a = Math.cbrt(100.90 + 150.10 - 220.50 + 10.50);
		System.out.println("Cube Root results = " + a);	

		System.out.println("\nCube Root of Zero: " + Math.sqrt(0));
		
		System.out.println("\nCube Root of Positive Number: " + Math.cbrt(64));
		System.out.println("Cube Root of Positive Number: " + Math.cbrt(100.95));
		
		System.out.println("\nCube Root of Negative Number: " + Math.cbrt(-850.70));
		System.out.println("Cube Root of Negative Number: " + Math.cbrt(-125.00));
	}
}

OUTPUT

Java cbrt Function 1

ANALYSIS

First, We declared variable of type Double and performed the Math.cbrt function directly on expression.

double a = Math.cbrt(100.90 + 150.10 - 220.50 + 10.50);
System.out.println("Cube Root results = " + a);

Next, We used the Math.cbrt Function directly on Positive double values.

System.out.println("\nCube Root of Positive Number: " + Math.cbrt(64));
System.out.println("Cube Root of Positive Number: " + Math.cbrt(100.95));

Next, We used the java Math.cbrt Function directly on Negative double values.

System.out.println("\nCube Root of Negative Number: " + Math.cbrt(-850.70));
System.out.println("Cube Root of Negative Number: " + Math.cbrt(-125.00));

Java cbrt on Array example

In this Java program we will show you, How to find the cube roots of bulk data. Here, we are going to declare an array of double type and find the cube root of each and every element in an array.

JAVA CODE

package MathFunctions;

public class CbrtOnArrays {
	public static void main(String[] args) {
		
		double [] CbrtArray = {27.00, 64.00, 125.00, -500.90, -124.8799, 1234.8597};

		for (int i = 0; i < CbrtArray.length; i++) {
			System.out.format("Cube Root of Array Element = %.4f\n", Math.cbrt(CbrtArray[i]));
		}
	}
}

OUTPUT

Java cbrt Function 2

ANALYSIS

First, We declared an Array of double type and assigned some random values.

double [] CbrtArray = {27.00, 64.00, 125.00, -500.90, -124.8799, 1234.8597};

Next, We used the Java For Loop to iterate the Array. Within the For Loop, we initialized the i value as 0. Next, compiler will check the condition (i < cbrtArray.length). As along the condition is True statement inside the for loop will be executed.

TIP: cbrtArray.length is used to find the length of an array.

for (int i = 0; i < CbrtArray.length; i++) {

Following statements will print the output. If you observe the code snippet, we used the Math.cbrt Function directly inside the System.out.format statement. Here, compiler will call the Java Math.cbrt method ( static double cbrt(double number) ) to find the cube root of corresponding values.

System.out.format("Cube Root of Array Element = %.4f\n", Math.cbrt(CbrtArray[i]));

NOTE: If you want to find the cube root of a single item then use: Math.cbrt(myArray[index_position])

Java cbrt function on Arraylist example

In this Java program we are going to declare an arraylist of double type and find the cube root of list elements.

JAVA CODE

package MathFunctions;

import java.util.ArrayList;

public class CbrtMethodOnArrayList {
	public static void main(String[] args) {
		
		ArrayList<Double> cbrtList = new ArrayList<Double>(5);
		cbrtList.add(12345.998);
		cbrtList.add(-180.05);
		cbrtList.add(1500.9876);
		cbrtList.add(1897.01);
		cbrtList.add(2596.98);
		cbrtList.add(-9878.1898);
		
		for (double x : cbrtList) {
			System.out.println("Cube Root of ArrayList =  " + Math.cbrt(x));
		}
	}
}

OUTPUT

Java cbrt Function 3

ANALYSIS

First, We declared an ArrayList of double type and assigned some random values.

ArrayList<Double> cbrtList = new ArrayList<Double>(5);
cbrtList.add(12345.998);
cbrtList.add(-180.05);
cbrtList.add(1500.9876);
cbrtList.add(1897.01);
cbrtList.add(2596.98);
cbrtList.add(-9878.1898);

Next, We used the For Loop to iterate the double values in ArrayList

for (double x : cbrtList) {

Following statements will print the output. If you observe the code snippet, we used the Math.cbrt Function directly inside the System.out.format statement. Here, compiler will call the java Math.cbrt method ( static double cbrt(double x) ) to find the cube root of corresponding values.

System.out.println("Cube Root of ArrayList =  " + Math.cbrt(x));
