note 107712 added to function.rand

I had to create a function that generates a random binominal distributed integer. Take a look at the following Wiki article: http://en.wikipedia.org/wiki/Binomial_distribution Here is my solution: <?php function bin_rand($min = null, $max = null) { $min = ($min) ? (int) $min : 0; $max = ($max) ? (int) $max : PHP_INT_MAX; $range = range($min, $max); $average = array_sum($range) / count($range); $dist = array(); for ($x = $min; $x <= $max; $x++) { $dist[$x] = -abs($average - $x) + $average + 1; } $map = array(); foreach ($dist as $int => $quantity) { for ($x = 0; $x < $quantity; $x++) { $map[] = $int; } } shuffle($map); return current($map); } ?> ---- Server IP: 69.147.83.197 Probable Submitter: 46.126.104.94 ---- Manual Page -- http://www.php.net/manual/en/function.rand.php Edit -- https://master.php.net/note/edit/107712 Del: integrated -- https://master.php.net/note/delete/107712/integrated Del: useless -- https://master.php.net/note/delete/107712/useless Del: bad code -- https://master.php.net/note/delete/107712/bad+code Del: spam -- https://master.php.net/note/delete/107712/spam Del: non-english -- https://master.php.net/note/delete/107712/non-english Del: in docs -- https://master.php.net/note/delete/107712/in+docs Del: other reasons-- https://master.php.net/note/delete/107712 Reject -- https://master.php.net/note/reject/107712 Search -- https://master.php.net/manage/user-notes.php
