You are confusing what a number is and how it is displayed. For example, Stata does not remove trailing zeros; it is just not displaying them with your format. You need to assign a format with leading zeros and two decimal places to get numbers displayed as you want. See -help format-. That said, you won't get exact arithmetic with such numeric variables unless your nunbers hold cents, not dollars.
