title: Ireport IF Else Expression
body: <p>I have this expression in iReport.:</p>
  
  <pre><code>($F{Q3_February}==0)?"-":$F{Q3_February}
  </code></pre>
  
  <p>Expression class is <code>Double</code>, I want this to returns as "-" if the value of <code>$F{Q3_February}</code> is <code>0</code>.</p>
  
  <p>I get "-" only if I change it to Expression class <code>String</code> but the problem is if the value is false it doesn't return a value of <code>#,##0.00 %</code></p>
