Binary "%" computes the modulus of two numbers.Given integer operands
$a and $b: If $b is positive, then "$a % $b" is $a minus the largest
multiple of $b that is not greater than $a. If $b is negative then
"$a % $b" is $a minus the smallest multiple of $b that is not less than
And... so what?
$a (i.e. the result will be less than or equal to zero). Note that
when "use integer" is in scope "%" gives you direct access to the mod-
ulus operator as implemented by your C compiler. This operator is not
as well defined for negative operands, but it will execute faster.
Is this the particular point on which you meant to draw the attention? If so, then it actually is a good point, however IMHO it belongs more to the realm of side notes...

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).
