title: QString::toDouble() giving me double with wrong precision
body: <p>I have a QString myNumber containing "09338.712001". When I do:</p>
  
  <p><code>myNumber.toDouble();</code>, it returns 9338.71, but I want the double to be the original value, which is 09338.712001. Does anyone know how to get the double returned by toDouble to have the same precision as the QString? Thanks. </p>
