Why does `encoding/binary` behave so weird?

<p>I have lets say the number <code>5000</code> when i encode it into bytes it should be <code>[]byte{136,19}</code> which comes from <code>[]byte{5e3&amp;0xff,5e3&gt;&gt;8}</code>.</p> <p>But golang results <code>[]byte{136,39}</code>. WTH is 39 i have no clue?</p> <hr/>**评论：**<br/><br/>dogestopmewow: <pre><p>Can you elaborate on what you&#39;re doing exactly, as I&#39;m unable to reproduce your problem?</p> <p>Here is an example where everything is working as expected: <a href="https://play.golang.org/p/6HnTt7SuYd_G" rel="nofollow">https://play.golang.org/p/6HnTt7SuYd_G</a></p></pre>korthaj: <pre><p>Perhaps you used one of the variable-length encoding functions by mistake?
