Bug #12612 Updated: unsigned integer problem

ID: 12612 Updated by: jeroen Reported By: dimon@postmark.net Old Status: Open Status: Analyzed Bug Type: Scripting Engine problem Operating System: Windows 2000 Server SP1 5.0.2195 PHP Version: 4.0.4pl1 New Comment: I wan't really clear on this one: PHP _does not support unsigned ints_ Generally, it support integers from -2147483648 to 2147483647 Previous Comments: ------------------------------------------------------------------------ [2001-08-07 16:54:30] jeroen@php.net PHP 4 handles number-constants smartly. I.e., when a number is out of range of integers, it will be auto-converted to float. var_dump(0x80000000) -> float(2147483648) While | requires int-arguments, and because it cannot convert float(2147483648) to int, it will take MAX_INT instead. That abs(MINIMAL_INT) bug, is a bug which I fixed yesterday (coincidence...) The 0x80000000 | 0; : apparently (int) 2147483648.0 => -2147483648 This IS a bug, because it should have been INT_MAX (2147483647) I'm currently trying to sort that out. By the way, do not put multiple bugs in one report. ------------------------------------------------------------------------ [2001-08-07 05:10:52] dimon@postmark.net $qq = 0x80000000; echo $qq; //2147483648 ok $qq = 0x80000000 | 0; echo $qq; //-2147483648 ??? echo abs($qq); //-2147483648 ??? echo $qq * -1; //2147483648 ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12612&edit=1
