#48496 [Opn]: String to numerical conversion

ID: 48496 Updated by: rquadling@php.net Reported By: headden at karelia dot ru Status: Open Bug Type: Documentation problem Operating System: Irrelevant PHP Version: Irrelevant New Comment: As 1234567890123 is larger than a 32bit integer, it is converted to a float. Once in a float it is quite happily allowed to be incremented as you are using.

Otherwise, it will be evaluated as an integer." this statement is wrong, consider the following code: $a = 1 + "1234567890123"; var_dump($a); // outputs 'float(1234567890124)' on a 32-bit platform this means that "1234567890123" was treated as 'float' although it does not have any of '.', 'e' or 'E' characters. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48496&edit=1
