The choice between print and printf depends on how badly you 'rely' on the format. The former usually does what you want with less effort. It may even be better for a special case that you forgot about. An occasional 'long number' may be annoying, but does no real harm if you are calculating the next move in your fantasy football game. In another application, the same behavior could spoil a whole batch of expensive forms (or worse). Clearly the latter is called for. They each have advantages. It is part of a Perl programmer's job to choose appropriately for each application.

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).
