Centering data is one thing you can use the Center icon just like your text.
Decimal point alignment is something else, use # to indicate optional
digits. You can see more examples in the table on my page
http://www.mvps.org/dmcritchie/excel/formula.htm#cellformat
format, cells, number (tab), custom
#,###.??? instead of #,###.00
If you want to keep it away from the right border then include _)
which simply means include a space as wide as close paren..
or any other character
#,###.???_)_0
