# Format calculated field in Base query

I have a decimal field in a query. Let's say 100.00. Then in a calculated field I multiply mentioned decimal field with let's say 1.3. Then that calculated field shows 130000 as a result. Why is that not 130.00? Or 130.000, if you like? In the corresponding field in a form it seems impossible to get 130.00 (format is with 2 decimals).
