Description: ------------ -0 is returns under the following example. I believe this is a bug. I see there was a bug about this a long time ago, But I think that the concept of a -0 is an invalid one. it just makes no sense. Even more if you consider that the following line will never gets executed if ($x < 0) //$x = -0 //NEVER EXECUTED if ($x <= 0) //$x = -0 //GETS EXECUTED Reproduce code: --------------- $i= (float) -90; $a= (int) 0; echo floor($i * ($a / 100)); returns -0;//MY OPINION IS AN ERROR $i= (int) -90; $a= (int) 0; echo floor($i * ($a / 100)); returns 0;//OK Expected result: ---------------- 0 should be returned always Actual result: -------------- -0 -- Edit bug report at http://bugs.php.net/?id=50622&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50622&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50622&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50622&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50622&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50622&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50622&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50622&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50622&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50622&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50622&r=support Expected behavior: http://bugs.php.net/fix.php?id=50622&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50622&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50622&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50622&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50622&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50622&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50622&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50622&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50622&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50622&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50622&r=mysqlcfg
