title: Compare int to NaN
body: <p>Using Titanium, is there a way to compare a TextField's value to NaN (not a number)? </p>
  
  <p>For example:</p>
  
  <pre><code>if (parseInt($.myTextField.value) == NaN)  
  </code></pre>
  
  <p>In this example, it doesn't enter the <em>if statement</em>.  I've also tried with '===' to no success.</p>
  
  <p>If I log the value converted to int it says "NaN"</p>
  
  <pre><code>Ti.API.info(parseInt($.myTextField.value));
  </code></pre>
  
  <p>Your input is appreciated!</p>
