Am I using the round function correctly?
<p>Here is my Perl code</p>

<pre><code>use POSIX;

my @arr = split(/\\n\\n/, $content);

my $len = length @arr;

$len = $len / 2;

my $b = round($len) - 1;
</code></pre>

<p>At the top of my script I have <code>use POSIX</code>. I once had <code>use Math::Round</code> but that didn't work.</p>

<p>I'm trying to use the <code>round</code> function but the page keeps breaking when I call it.</p>
