I would not normally post such a simple question but:

• I'm no regex wiz.
• I'm under a time constraint (I need this before the end of today) and need to work on other aspects of the same project in the meantime.
• This is to go into production code so I'd prefer a more optimized, clean solution and not the quick, dirty ugly one below.

My current *debugging* code:

use strict;

while (<DATA>) {
   chomp;
   my $input = $_;
   tr/$, +//d;
   if (/^[-]?\d+$/) {
      print "Acceptable: '$input' -> $_\n";
   } elsif (/^[-]?\d+\.[\d]+$/) {  ## problem
      print "Acceptable: '$input' -> ", int $_, "\n";
   } else {
      print "Not acceptable: '$input' -> $_\n";
   }
}

__DATA__
+30
-400
+20,0
-300.02
$ -50.1
-$ 500
- $ 60
 + $ 30.

All the example data is acceptable. I don't need a one-regex-fits-all solution--readability is more important. Rounding is unnecessary. Blanks outside of the numeric component are allowable but should be eliminated from the results. I'm not sure how to correct *problem* expression to handle the last test case (and it may allow undesirable things I'm not aware of). Here is the output from the above code:

Acceptable: '-400' -> -400
Acceptable: '+20,0' -> 200
Acceptable: '-300.02' -> -300
Acceptable: '$ -50.1' -> -50
Acceptable: '-$ 500' -> -500
Acceptable: '- $ 60' -> -60
Not acceptable: ' + $ 30.' -> 30.

Thanks in advance for any help!
