note 20240 added to language.operators.bitwise

Be careful with using Bitwise operators with Floating point numbers. You can set bits up to 31th bit (including) - in this case the value is internally stored as integer. When you try to set 32th bit or higher the variable changes its type to floating point number. When you try to test any bit of floating point variable you always get the same result - bit is set to 1 (it behaves like all 64 bits are set to 1). -- http://www.php.net/manual/en/language.operators.bitwise.php http://master.php.net/manage/user-notes.php?action=edit+20240 http://master.php.net/manage/user-notes.php?action=delete+20240 http://master.php.net/manage/user-notes.php?action=reject+20240
