I assume you just want to "nullify" the last 3 digits of your numbers. You could do it with the following code: 

my @strings=("500", "988", "1210", "1300", "2000");

foreach my $in (@strings)
{
    print "$in ";
    $in =~ s/(\d\d\d)$/000/;  # take the last 3 digits, replace them w
+ith 000
    print "-> $in\n";
}
