title: Equation doesn't add up? PHP
body: <p>I'm stuck!</p>
  
  <p>When I run the code it echos 82374928408977024.
  But I know for a fact (or at least im pretty sure) that 15323523 *2 + 82374928378329992 equals to 82374928408977038.
  Too large strings? In addition, I would like to echo the result in a plain number format without scientific notations.</p>
  
  <pre><code>&lt;?php
  $number = "15323523";
  $result = $number * 2 + 82374928378329992;
  echo sprintf('%f', $result);
  ?&gt;
  </code></pre>
  
  <p>Thanks a bunch to anyone who can help me with this.</p>
