#41038 [Opn->WFx]: Problem with PHP parser in handling MIN_INT value.

ID: 41038 Updated by: tony2001@php.net Reported By: mahesh dot vemula at in dot ibm dot com -Status: Open +Status: Wont fix Bug Type: *Compile Issues Operating System: RHEL 4 PHP Version: 5CVS-2007-04-10 (snap) New Comment: String "-2147483648" contains two tokens: "-" and "2147483648". Since strtol() returns ERANGE when parsing "2147483648", the result number is double. From what I can see, changing this fact would require major changes to the parser which hopefully nobody is going to do. Marking as "Won't fix". Previous Comments: ------------------------------------------------------------------------ [2007-04-10 12:58:00] mahesh dot vemula at in dot ibm dot com Description: ------------ The least integer value (i.e -2147483648 ) is being treated as float(-2147483648) by the parser. var_dump(-2147483648) returns float(-2147483648). A integer value should be treated as float, only if the value is beyond the boundary of the integer type. The php documentation explains the same here : http://in.php.net/manual/en/function.intval.php & http://in.php.net/manual/en/language.types.integer.php Remarks: The Reproduce code confirms that the parser is not handling the Minimum Integer value (i.e, -2147483648) as expected. Environment: Operating System: RHEL 4 Linux Kernel : Linux 2.6.9 PHP Version: PHP 5.2 (Built on Apr 10, 2007 from snaps.php.net) PHP Configure Setup: ./configure Reproduce code: --------------- <?php $i = -2147483648; var_dump($i); $j = (int)"-2147483648"; var_dump($j); ?> Expected result: ---------------- int(-2147483648) int(-2147483648) Actual result: -------------- float(-2147483648) int(-2147483648) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41038&edit=1
