title: Does negative int number from exception indicates more than just a number?
body: <p>Simple code indeed : </p>
  
  <pre><code>int number = int.MaxValue;
      number = number+1;
  Console.WriteLine(number);
  </code></pre>
  
  <p>Questions : </p>
  
  <p>1) there's should be overflowException. there isn't. why is that?</p>
  
  <p>2) Does the number <code>-2147483648</code> indicates something about : </p>
  
  <ul>
  <li><p>) how many bytes is beyond limit size  ?</p></li>
  <li><p>) if i see <code>-2147483648</code>  , How can I know ( if there wasnt an exception) - if this number came from exception ? - must I wrap it with Try Catch ?</p></li>
  </ul>
  
  <p>p.s.  when i wrote : </p>
  
  <pre><code>int number = int.MinValue;
      number = number-1;
  Console.WriteLine(--number);
  </code></pre>
  
  <p>I got  : <code>2147483647</code> (still no exception).</p>
