title: Always show decimal places in SQL?
body: <p>I'm working on a query which returns numeric values (currency).  Some of the values are whole numbers and are being displayed as 3, 5, 2 etc whilst other numbers are coming up like 2.52, 4.50 etc.</p>
  
  <p>How can I force oracle to always show the decimal places?</p>
  
  <p>Thanks</p>
