note 92157 added to function.sprintf

I had a nightmare trying to find the two's complement of a 32 bit number. I got this from http://www.webmasterworld.com/forum88/13334.htm (credit where credit is due... =P ) Quote: ...find out the 2's complement of any number, which is -(pow(2, n) - N) where n is the number of bits and N is the number for which to find out its 2's complement. This worked magic for me... previously I was trying to use sprintf ("%b",$32BitDecimal); But it always returned 10000000000000000000000 when the $32BitDecimal value got above 2,000,000,000. This -(pow(2, n) - N) Worked remarkably well and was very accurate. Hope this helps someone fighting with two's complement in PHP. ---- Server IP: 64.71.164.2 Probable Submitter: 99.50.206.103 ---- Manual Page -- http://www.php.net/manual/en/function.sprintf.php Edit -- https://master.php.net/note/edit/92157 Del: integrated -- https://master.php.net/note/delete/92157/integrated Del: useless -- https://master.php.net/note/delete/92157/useless Del: bad code -- https://master.php.net/note/delete/92157/bad+code Del: spam -- https://master.php.net/note/delete/92157/spam Del: non-english -- https://master.php.net/note/delete/92157/non-english Del: in docs -- https://master.php.net/note/delete/92157/in+docs Del: other reasons-- https://master.php.net/note/delete/92157 Reject -- https://master.php.net/note/reject/92157 Search -- https://master.php.net/manage/user-notes.php
