How do I increase the number of decimal places shown?

Hi,

How do I increase the number of decimal places from 2 to 4 and prevent rounding? For that matter how do I access the formatting for a cell such a font, type, etc. I tried right clicking nothing except removal of formatting. When I click on a cell the proper number shows in the status line but within the document it is truncated to 2 decimal places.

Thanks
