note 118074 added to math.constants

I just learnt of INF today and found out that it can be used in comparisons: echo 5000 < INF ? 'yes' : 'no'; // outputs 'yes' echo INF < INF ? 'yes' : 'no'; // outputs 'no' echo INF <= INF ? 'yes' : 'no'; // outputs 'yes' echo INF == INF ? 'yes' : 'no'; // outputs 'yes' You can also take its negative: echo -INF < -5000 ? 'yes' : 'no'; // outputs 'yes' Division by INF is allowed: echo 1/INF; // outputs '0' ---- Server IP: 72.52.91.14 Probable Submitter: 83.140.140.170 ---- Manual Page -- http://php.net/manual/en/math.constants.php Edit -- https://master.php.net/note/edit/118074 Del: integrated -- https://master.php.net/note/delete/118074/integrated Del: useless -- https://master.php.net/note/delete/118074/useless Del: bad code -- https://master.php.net/note/delete/118074/bad+code Del: spam -- https://master.php.net/note/delete/118074/spam Del: non-english -- https://master.php.net/note/delete/118074/non-english Del: in docs -- https://master.php.net/note/delete/118074/in+docs Del: other reasons-- https://master.php.net/note/delete/118074 Reject -- https://master.php.net/note/reject/118074 Search -- https://master.php.net/manage/user-notes.php
