note 82714 added to function.bcmul

Does the bcmul use karatsuba method for multiplication, or is it the normal way of O(n^2). I want to multiply numbers which have sizes of 10,000 digits. Where can i contribute to this library. So i can add more functions? ---- Server IP: 117.104.160.194 Probable Submitter: 149.171.6.250 ---- Manual Page -- http://www.php.net/manual/en/function.bcmul.php Edit -- https://master.php.net/note/edit/82714 Del: integrated -- https://master.php.net/note/delete/82714/integrated Del: useless -- https://master.php.net/note/delete/82714/useless Del: bad code -- https://master.php.net/note/delete/82714/bad+code Del: spam -- https://master.php.net/note/delete/82714/spam Del: non-english -- https://master.php.net/note/delete/82714/non-english Del: in docs -- https://master.php.net/note/delete/82714/in+docs Del: other reasons-- https://master.php.net/note/delete/82714 Reject -- https://master.php.net/note/reject/82714 Search -- https://master.php.net/manage/user-notes.php
