Commify text

| Computers and stuff | 2 Comments

Here's a little Perl snippet which will place commas in any number string right where they belong:

sub commify
    my $text = reverse $_[0];
    $text =~ s/(\d\d\d)(?=\d)(?!\d*\.)/$1,/g;
    return scalar reverse $text;

So for example, by calling commify("13245766") the value "13,245,766" will be returned.

All the little commas right exactly at the correct positions using a simple regular expression. Pretty amazing language that Perl is. Does it make sense?


how to convert "13,245,766" bach to number??

The answer is simple: "$text =~ s/,//g;" (hope this helps).
