title: Determining if a string is not null/blank and is a number and not 0?
body: <p>I normally don't work in ColdFusion but there's a FTP process at work I have to create a report for with the only option right now being a ColdFusion 8 server.   This FTP feed has a few issues (trash too).</p>
  
  <p>So, I make the query and then I need to convert some of the string values during the output to do some math.   Before that:</p>
  
  <p>How do I tell if a field in the output loop:  is not blank or null, is string that can be converted into a valid number, and is not 0?</p>
  
  <p>Is there a simple way of doing this w/o a lot of if statements?</p>
  
  <p>Thanks!</p>
