title: Examples of doing decimal math in iPhone
body: <p>I'm pulling decimal values from a sql table as a text field which i then convert to an NSDecimalNumber (this is simply because i didnt know read/write decimal values to sqllite).</p>
  
  <p>Anyway, now i've hit a wall now that im trying to do simple math routines on these decimal variables. Such as, Sum = Balance * Interest_Rate. The idea is that im working with money calculations.</p>
  
  <p>Do you know of samples/tutorials that teaches how to do these operations using either NSDecimal, NSDecimalNumber, or both?</p>
  
  <p>Thanks.</p>
