From: d_kelsey at uk dot ibm dot com Operating system: Linux 64Bit PHP version: 5.2CVS-2009-02-17 (CVS) PHP Bug Type: Scripting Engine problem Bug description: not operator does a c cast to long which is different to other ops Description: ------------ In zend_operators.c the function ZEND_API int bitwise_not_function(..) handles a double by doing a c cast to a long "if (op1->type == IS_DOUBLE) { op1->value.lval = (long) op1->value.dval; op1->type = IS_LONG; }" but all other operators use the zendi_convert_to_long() macro so not isn't consistent with the other operators. this can result in an unexpected value as shown in the test case Reproduce code: --------------- <?php define("MAX_64Bit", 9223372036854775807); $e = (MAX_64Bit + 1); $f = (int)$e; var_dump(~(MAX_64Bit + 1)); var_dump(~$f); ?> Expected result: ---------------- int(-9223372036854775808) int(-9223372036854775808) Actual result: -------------- int(9223372036854775807) int(-9223372036854775808) -- Edit bug report at http://bugs.php.net/?id=47424&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47424&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47424&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47424&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47424&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47424&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47424&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47424&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47424&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47424&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47424&r=support Expected behavior: http://bugs.php.net/fix.php?id=47424&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47424&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47424&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47424&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47424&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47424&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47424&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47424&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47424&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47424&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47424&r=mysqlcfg
