Displaying decimals in JavaScript??

Oct 8th, 2008

I am new to JavaScript and have what may be a very simple and easy question to most. I am writing a simple block of code that I need to display dollar amounts with 2 decimals for change. For example instead of displaying the number 5, I need it to display 5.00. How can I do this? Any help will be greatly appreciated.
