From: mccohy at kyberdigi dot cz Operating system: Linux PHP version: 5.0.2 PHP Bug Type: Math related Bug description: Bitwise operator returns unwanted values
Description: ------------ The bitwise operator "and" returns an unwanted value. Here is a simple example: Let's store value 924303769 in variable $a and value -2147483649 in variable $ax. Now, let's count the 'bitwise and' of these two variables ($a & $ax). PHP 5.0.2 returns zero. PHP 4.3.9 returns 924303769. I am not sure what happens in 5.0.0 or 5.0.1, sorry. Reproduce code: --------------- $a=924303769; $ax=-2147483649; echo ($a & $ax)."\n"; Expected result: ---------------- 924303769 Actual result: -------------- 0 -- Edit bug report at http://bugs.php.net/?id=30271&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=30271&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=30271&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=30271&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=30271&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=30271&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=30271&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=30271&r=needscript Try newer version: http://bugs.php.net/fix.php?id=30271&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=30271&r=support Expected behavior: http://bugs.php.net/fix.php?id=30271&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=30271&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=30271&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=30271&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=30271&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=30271&r=dst IIS Stability: http://bugs.php.net/fix.php?id=30271&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=30271&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=30271&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=30271&r=mysqlcfg
