Computer Applications
Write a program to input a number and evaluate the results based on the number entered by the user:
(a) Natural logarithm of the number
(b) Absolute value of the number
(c) Square root of the number
(d) Cube of the number
(e) Random numbers between 0 (zero) and 1 (one).
Answer
import java.util.Scanner;
public class KboatMathMethods
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter Number: ");
double n = in.nextDouble();
System.out.println("Natural logarithm = " + Math.log(n));
System.out.println("Absolute value = " + Math.abs(n));
System.out.println("Square root = " + Math.sqrt(n));
System.out.println("Cube root= " + Math.cbrt(n));
System.out.println("Random number = " + Math.random());
