note 129741 added to function.stats-dens-normal

If you don't have the stats package and can't install it, I have found this to work: <?php if (!function_exists('stats_dens_normal')) { function stats_dens_normal(float $x, float $ave, float $stdev): float { $A = $stdev * sqrt(2 * M_PI); $B = -pow($x - $ave, 2); $C = 2 * pow($stdev, 2); return (1 / $A) * pow(M_E, $B / $C); } } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 203.97.21.86) ---- Manual Page -- https://php.net/manual/en/function.stats-dens-normal.php Edit -- https://main.php.net/note/edit/129741 Del: integrated -- https://main.php.net/note/delete/129741/integrated Del: useless -- https://main.php.net/note/delete/129741/useless Del: bad code -- https://main.php.net/note/delete/129741/bad+code Del: spam -- https://main.php.net/note/delete/129741/spam Del: non-english -- https://main.php.net/note/delete/129741/non-english Del: in docs -- https://main.php.net/note/delete/129741/in+docs Del: other reasons-- https://main.php.net/note/delete/129741 Reject -- https://main.php.net/note/reject/129741 Search -- https://main.php.net/manage/user-notes.php
