How can I round a number to the nearest number evenly divisible by 16?
<p>I have a simple round function. It rounds to an even number. I want to make sure that number is divisible by 16. Anyone know an easy way to round the number to the nearest number divisible evenly by 16?</p>

<pre><code>$num=round(480/$other_num); //will output some number.
</code></pre>
