Changed
my $nextidx = $asize / 2; my $nextinc = $nextidx / 2;
to:
my $nextidx = int($asize / 2); my $nextinc = int($nextidx / 2);
(Otherwise, for an array of 5 elements, it’d return an index = 2.5 ;-...)).
Actually, that change is unnecessary. Whenever a floating point value is used as an array index, Perl automatically
uses just the integer part of the value, since that would be the only sensible thing to do.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
