note 72383 added to function.crc32

Oops. Description of factorization of polynomials is wrong: it is over the integers modulo two, so (x^2 + 1) factors into (x+1)*(x+1), not (x+1)*(x-1). (x+1)*(x+1) = (x^2 + 2x + 1) = (x^2 + 0x + 1) (since integers are modulo 2). ---- Server IP: 216.194.113.175 Probable Submitter: 24.9.89.42 ---- Manual Page -- http://www.php.net/manual/en/function.crc32.php Edit -- https://master.php.net/note/edit/72383 Del: integrated -- https://master.php.net/note/delete/72383/integrated Del: useless -- https://master.php.net/note/delete/72383/useless Del: bad code -- https://master.php.net/note/delete/72383/bad+code Del: spam -- https://master.php.net/note/delete/72383/spam Del: non-english -- https://master.php.net/note/delete/72383/non-english Del: in docs -- https://master.php.net/note/delete/72383/in+docs Del: other reasons-- https://master.php.net/note/delete/72383 Reject -- https://master.php.net/note/reject/72383 Search -- https://master.php.net/manage/user-notes.php
