title: What is the method to get a REAL from SUM using ORMLite
body: <p>I have various <code>double</code> values in my database. To get the sum of them all I am using </p>
  
  <p><code>relvantDao.queryRawValue("SELECT SUM(productPrice * productQuantity) FROM cart");</code></p>
  
  <p>Problem is that this only returns a <code>long</code> value, hence the decimal points are lost. How can I get the <code>REAL</code> sum of these values?</p>
