squaring a number and odd integers

what symbol is used to square a number I thought it would be this symbol ^ but that does not work from what I've try. Also is it possible to just have display odd integers. Even if some one new a site that would explain it that would be great.

Take a look at the Math class.
Odd integers are the ones that have a remainder when you divide them by 2.
If ( x % 2 == 1 ) // then it's odd

http://java.sun.com/docs/books/tutorial/java/nutsandbolts/opsummary.html might help (but there's no square operator). Of course, you can always multiply the number by itself.

You could do this:
double d = Math.pow(myNum, 2.0d);

By the way, the ^ means "exclusive or".

Running the risk of asking a stupid question: What is the difference between using Math.pow() & Math.exp()? :roll:

Math.exp(3) = e to the third power.
