Question

The following seems to match ,
Can someone explain why?

I would like to match more than one Number or point, ended by comma.

 123.456.768,
 123,
 .,
 1.2,

But doing the following unexpectedly prints , too

my $text = "241.000,00";
foreach my $match ($text =~ /[0-9\.]+(\,)/g){
    print "$match \n";
}
print $text; 

# prints 241.000,
#        ,

Update:
The comma matched because:
In list context, //g returns a list of matched groupings, or if there are no groupings, a list of matches to the whole regex
As defined here.

Answer 1

Use a zero-width positive look-ahead assertion to exclude the comma from the match itself:

$text =~ /[0-9\.]+(?=,)/g
