PHP rounding, round/ceil/floor??
<p>Say I have the two following numbers:</p>

<pre><code>$a = 77.5;
$b = 74.5;
</code></pre>

<p>How would I get the following:</p>

<pre><code>$a = 80;
$b = 70;
</code></pre>

<p>I have looked at round, ceil and floor but I can't figure out how to do it.</p>

<p>Thank you.</p>
