body: <p>What actually happens when a Byte overflows?</p>
  
  <p>Say we have</p>
  
  <pre><code>byte byte1 = 150; // 10010110  
  byte byte2 = 199; // 11000111
  </code></pre>
  
  <p>If we now do this addition</p>
  
  <pre><code>byte byte3 = byte1 + byte2;
  </code></pre>
  
  <p>I think we'll end up with byte3 = 94 but what actually happens? Did I overwrite some other memory somehow or is this totally harmless?</p>
