Appears not to work if there's a decimal '.' ? Or a sign ?

Just for the hell of it:

use strict ; use warnings ; foreach my $t (1234567, 123.4567, -123456, .123456, '.1234567', -10* +*1000) { printf "%12s -> oko1:%12s, faq:%12s\n", $t, commify($t), commify_f +aq($t) ; } ; sub commify { my ($s) = @_ ; my @list = () ; my $c = 0 ; for (reverse split //, $s){ unshift @list, $c++ % 3 || $c == 1 ? $_ : "$_,"; } ; return join '', @list ; } ; sub commify_faq { local $_ = shift ; 1 while s/^([-+]?\d+)(\d{3})/$1,$2/ ; return $_ ; } ;
gives:
     1234567 -> oko1:   1,234,567, faq:   1,234,567
    123.4567 -> oko1:  12,3.4,567, faq:    123.4567
     -123456 -> oko1:   -,123,456, faq:    -123,456
    0.123456 -> oko1:  0.,123,456, faq:    0.123456
    .1234567 -> oko1:  .1,234,567, faq:    .1234567
        -inf -> oko1:       -,inf, faq:        -inf
which, from a pedagogical stand point, may be useful in itself :-)
