note 113703 added to language.types.float

$x = 8 - 6.4; // which is equal to 1.6 $y = 1.6; var_dump($x == $y); // is not true PHP thinks that 1.6 (coming from a difference) is not equal to 1.6. To make it work, use round() var_dump(round($x, 2) == round($y, 2)); // this is true This happens probably because $x is not really 1.6, but 1.599999.. and var_dump shows it to you as being 1.6. ---- Server IP: 72.52.91.14 Probable Submitter: 72.52.91.14 ---- Manual Page -- http://php.net/manual/en/language.types.float.php Edit -- https://master.php.net/note/edit/113703 Del: integrated -- https://master.php.net/note/delete/113703/integrated Del: useless -- https://master.php.net/note/delete/113703/useless Del: bad code -- https://master.php.net/note/delete/113703/bad+code Del: spam -- https://master.php.net/note/delete/113703/spam Del: non-english -- https://master.php.net/note/delete/113703/non-english Del: in docs -- https://master.php.net/note/delete/113703/in+docs Del: other reasons-- https://master.php.net/note/delete/113703 Reject -- https://master.php.net/note/reject/113703 Search -- https://master.php.net/manage/user-notes.php
