note 124889 added to function.gmp-invert

Example #2 gmp_invert() example <?php echo gmp_invert("5", "10"); // no inverse, outputs nothing, result is FALSE It means (5 * x ) mod 10 = 1. And with this function we want a value for x, because of mod 10, x should be {1.. 10-1(9)}, so : 5 * 1 mod 10 = 5 5 * 2 mod 10 = 0 5 * 3 mod 10 = 5 5 * 4 mod 10 = 0 5 * 5 mod 10 = 5 5 * 6 mod 10 = 0 5 * 7 mod 10 = 5 5 * 8 mod 10 = 0 5 * 9 mod 10 = 5 We don't have any 1 in the results. so it will be False. $invert = gmp_invert("5", "11"); echo gmp_strval($invert) . "\n"; ?> The above example will output: 9 5 * 9 mod 11 = 1 ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 185.2.82.49) ---- Manual Page -- http://php.net/manual/en/function.gmp-invert.php Edit -- https://master.php.net/note/edit/124889 Del: integrated -- https://master.php.net/note/delete/124889/integrated Del: useless -- https://master.php.net/note/delete/124889/useless Del: bad code -- https://master.php.net/note/delete/124889/bad+code Del: spam -- https://master.php.net/note/delete/124889/spam Del: non-english -- https://master.php.net/note/delete/124889/non-english Del: in docs -- https://master.php.net/note/delete/124889/in+docs Del: other reasons-- https://master.php.net/note/delete/124889 Reject -- https://master.php.net/note/reject/124889 Search -- https://master.php.net/manage/user-notes.php
