title: Am I using the round function correctly?
body: <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>
