Exponent Problem

[Kevin Marois]

Notice the comments. What's wrong here?

import java.lang.*;
import java.lang.Math.*;

public class Exponent
{
public static void main(String[] args)
{
int iBase = 10;
int iExponent = 2;

	double dCubed = Math.pow ( iBase, iExponent); // Produces 100.0
	System.out.println( dCubed );
	
	
	int iResult = iBase ^ iExponent; // Produces 8
	System.out.println( iResult );
	

}

In Java, the ' ^ ' is a bitwise operator, not a power operator!

Which does exactly what?

Gosh, all I did was go to "java.sun.com" --- all the answers are RIGHT THERE! Here! I did it for you: The bitwise ^ operator performs a bitwise exclusive OR operation. So 10 = 1010 2 = 0010 Exclusive OR = 1000 = decimal 8!

I looked it up too. I don't understand what 'bitwise' means. It it was so much trouble for you, why bother responding at all?

if it's too much for you to 1) search the web, 2) read the docs, and 3) try to understand a wise answer you got, why bothering asking ? bitwise operators are operators operating directly on the bits rather than full bytes. so, as the other guy was saying, the ^ operator is the XOR (exclusive OR) bitwise operator.

10 = 1010
2 = 0010

^ 1000 -> 8
