note 83790 added to language.types.integer

In response to the comment by me at troyswanson dot net: -2147483648 falls into the range of 32 bit signed integers yet php treats it as a float. However, -2147483647-1 is treated as an integer. The following code demonstrates: <?php var_dump(-2147483648); //float(-2147483648) var_dump(-2147483647 - 1); //int(-2147483648) ?> This is probably very similar to the MS C bug which also treats -2147483648 as an UNSIGNED because it thinks it's out of the range of a signed int. The problem is that the parser does not view "-x" as a single token, but rather as two, "-" and "x". Since "x" is out of the range of an INT, it is promoted to float, even though in this unique case, "-x" is in the range of an int. The best cure is probably to replace "-2147483648" with "0x80000000", as that is the hexadecimal equivalent of the same number. Hope that helps explain what's going on Peace - Eric / fez ---- Server IP: 64.71.164.2 Probable Submitter: 128.101.8.116 ---- Manual Page -- http://www.php.net/manual/en/language.types.integer.php Edit -- https://master.php.net/note/edit/83790 Del: integrated -- https://master.php.net/note/delete/83790/integrated Del: useless -- https://master.php.net/note/delete/83790/useless Del: bad code -- https://master.php.net/note/delete/83790/bad+code Del: spam -- https://master.php.net/note/delete/83790/spam Del: non-english -- https://master.php.net/note/delete/83790/non-english Del: in docs -- https://master.php.net/note/delete/83790/in+docs Del: other reasons-- https://master.php.net/note/delete/83790 Reject -- https://master.php.net/note/reject/83790 Search -- https://master.php.net/manage/user-notes.php
