"\n--------\n"; echo 'pow=' . $pow . "\n"; echo 'prop=' . $prop . "\n------\n"; } } ?> ---- Server IP: 147.32.160.17 Probable Submitter: 147.32.122.190 ---- Manual Page -- http://www.php.net/manual/en/function.gmp-prob-prime.php Edit -- https://master.php.net/note/edit/104393 Del: integrated -- https://master.php.net/note/delete/104393/integrated Del: useless -- https://master.php.net/note/delete/104393/useless Del: bad code -- https://master.php.net/note/delete/104393/bad+code Del: spam -- https://master.php.net/note/delete/104393/spam Del: non-english -- https://master.php.net/note/delete/104393/non-english Del: in docs -- https://master.php.net/note/delete/104393/in+docs Del: other reasons-- https://master.php.net/note/delete/104393 Reject -- https://master.php.net/note/reject/104393 Search -- https://master.php.net/manage/user-notes.php
