Setting decimal place for each row in a column

[jfg]

I have Excel 2003. I a column containing 30 rows. I would like the numbers in
each row of the column to be to two decimal places, i.e., xxx.yy. I am
currently in row 2 of the column. What do I do to automatically general
number to two decimal places in the remaining 28 rows?

Thank you.
