title: C#/QML types convertion (double/real/float)
body: <p>my C# project is reading some configurations from a QML file.</p>
  
  <p>The thing is that i'm not sure about some convertions...</p>
  
  <pre><code>QML        C#
  int    &lt;-&gt; int
  string &lt;-&gt; string
  bool   &lt;-&gt; bool
  </code></pre>
  
  <p>are OK</p>
  
  <p>I'm not sure about real/double in QML (to float/double in C#)
  I looked for some info about precisions but didn't find anything very clear.</p>
  
  <p>Does double in QML is equivalent to double in C# ?
  Does real in QML is equivalent to float in C# ?</p>
