note 124860 added to function.pi

the documentation is wrong, pi()'s return value has nothing to do with the precision ini-setting, at least on 64bit amd64 php 7.3.7, pi() always return 3.141592653589793115997963468544185161590576171875 , no matter what the precision is set to. you can easily test this yourself with: <?php ini_set("precision","2"); $answer=3.141592653589793115997963468544185161590576171875; var_dump( pi() === $answer, number_format(pi(),99,".","") ); ?> ---- Server IP: 45.112.84.4 Probable Submitter: 185.85.3.195 (proxied: 46.46.205.247) ---- Manual Page -- http://php.net/manual/en/function.pi.php Edit -- https://master.php.net/note/edit/124860 Del: integrated -- https://master.php.net/note/delete/124860/integrated Del: useless -- https://master.php.net/note/delete/124860/useless Del: bad code -- https://master.php.net/note/delete/124860/bad+code Del: spam -- https://master.php.net/note/delete/124860/spam Del: non-english -- https://master.php.net/note/delete/124860/non-english Del: in docs -- https://master.php.net/note/delete/124860/in+docs Del: other reasons-- https://master.php.net/note/delete/124860 Reject -- https://master.php.net/note/reject/124860 Search -- https://master.php.net/manage/user-notes.php
