title: How to parse a String to a long with no loss
body: <p>I'm having an issue when parsing a string to a long. I want the variable "695690829980893234" to be parsed to a long without any loss. I've looked around for a bit but nothing really seemed to have helped. </p>
  
  <p>When using <code>(double) $var</code> it shows as a 4.2904753172133E+17 (which is not the way I need it)</p>
  
  <p>Does anyone have any ideas? Much appreciated!</p>
