I need to build a calculator using Javascript. There is an HTML file provided with most of the calculator already being created, however it still needs a decimal button. I can't figure out how to add this button. I'd like to have it placed next to the "0" if possible.

Below is the code that I already have:

			Clear
1	2	3	+
4	5	6	-
7	8	9	*
0	=	/
