title: int16 to byte array
body: <p>I'm trying to convert a int16 to a byte array but i cant seem to get it to work.<br />
  Here is what i've got right now:</p>
  
  <pre><code>int16 i := 41
  a := []byte(string(i))//this line is wrong
  </code></pre>
  
  <p>Also if someone wonder the array needs to be a length of 2.</p>
