in thread long integer to hexadecimal conversion

Much simpler:

use bigint; my $n = 123456789123456; print $n->as_hex;
or just
use bigint; print 123456789123456->as_hex

    True.

    You'd only need my algorithm if you wanted to express the integer in a base other than 16 (or 8).

    use bigint; my @digits=map chr,(0x30..0x39,0x41..0x5d); my $base = 22; my $n = 123456789123456; my $h; while($n > 0){ $h .= $digits[ $n % $base ]; $n /= $base; } print scalar reverse $h';
    Result is 4E5G93GHBE8.
