Bug #53934 [NEW]: The negative PHP_INT_MAX is incorrectly converted to float

From: Operating system: Linux PHP version: 5.3.5 Package: Scripting Engine problem Bug Type: Bug Bug description:The negative PHP_INT_MAX is incorrectly converted to float Description: ------------ I found this and seems a bug. Everytime I use the negative PHP_INT_MAX literally (-9223372036854775808) as a function parameter, it is converted to float. However, if I pass it like an expression -9223372036854775807 - 1, it is correctly identified as an integer. Test script: --------------- --TEST-- Checks if the negative PHP_INT_MAX is treated as integer. --CREDITS-- Eriksen Costa <eriksen.costa@infranology.com.br> --SKIPIF-- <?php if (PHP_INT_SIZE < 8) die('64bit platforms only'); ?> --FILE-- <?php var_dump(-9223372036854775807 - 1); var_dump((PHP_INT_MAX * -1) - 1); var_dump(-9223372036854775808); ?> --EXPECT-- int(-9223372036854775808); int(-9223372036854775808); int(-9223372036854775808); Expected result: ---------------- int(-9223372036854775808); int(-9223372036854775808); int(-9223372036854775808); Actual result: -------------- int(-9223372036854775808) int(-9223372036854775808) float(-9.2233720368548E+18) -- Edit bug report at http://bugs.php.net/bug.php?id=53934&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53934&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53934&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53934&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53934&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53934&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53934&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53934&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53934&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53934&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53934&r=support Expected behavior: http://bugs.php.net/fix.php?id=53934&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53934&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53934&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53934&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53934&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53934&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53934&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53934&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53934&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53934&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53934&r=mysqlcfg
