Dear Monks,
I want your help for a minor querry!!!
In the perl programme I want to get some input (numeric) from the user.
After that I store in in $a Now how should I check whether the input is a
number or not... for ex. it may be like 987fsfh{ etc .
One way which I could think of is to chop the $a till it becomes empty &
see that the all characters return when chopping match between digits from
0 to 9 with one of them can be . but is there a smarter way out as it is
very redundant & long way of doing it...
Thanks,
VNPAndey

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).

or How to display code and escape characters
are good places to start.
