Hi Monks,
I am trying to distinguish between numeric and string scalar values using regular expression as the below code.
my $var = {
'key1' => '1',
'key2' => 1
};
print "Key1: It is a number\n" if ( $var->{'key1'} =~ /^-?\d/ ) ;
print "Key2: It is a number\n" if ( $var->{'key2'} =~ /^-?\d/ ) ;
But it is always getting interpreted as a number.
Could somebody help me distinguish between the values '1' and 1 as in the above code

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).

are good places to start.
