What number does 8e3 evaluate to?
<p>I encountered this code today:</p>

<pre><code>b = setTimeout(function () {
    // do some javascript stuff here
}, 8e3)
</code></pre>

<p>The timeout is set to <code>8e3</code>.  What time does this equate to in milliseconds, and why would anyone choose this strange notation?  The code appears to be fully functional.</p>
