Problem with factorial operator - Mailing list pgsql-general

Hi all,

The PG Documentation states:


tgl=> select cast(text '44' as int8) ! as "factorial";
      factorial
---------------------
 2673996885588443136
(1 row)


If you try it, you will get the same result, but it is the wrong answer.
Factorial work up to 20. After that one gets negative results.
