ID: 51274 Updated by: ahar...@php.net Reported by: cduncan at regatta dot com Summary: Integer overflow does not cast as float -Status: Feedback +Status: Open Type: Bug Package: *General Issues Operating System: Linux PHP Version: 5.3.2 New Comment: Oh, I see what you're getting at now. Sorry about that. I still can't reproduce it, though. Previous Comments: ------------------------------------------------------------------------ [2010-03-26 09:16:37] cduncan at regatta dot com Sorry but I'm misunderstanding what you are telling me. Why is the number reduced to the 32bit limit? (2147483647) Especially if you're saying the only way this could occur is with a 64bit OS? As I stated in my last edit, wouldn't a 64bit OS return: int(2147483648) ------------------------------------------------------------------------ [2010-03-26 07:50:20] ahar...@php.net Automatic comment from SVN on behalf of aharvey Revision: http://svn.php.net/viewvc/?view=revision&revision=296829 Log: Update to the integer type page to make it clearer how overflow works on 32- and 64-bit systems and what the critical thresholds are. Prompted by bug #51274, although not an actual fix for it. ------------------------------------------------------------------------ [2010-03-26 06:33:35] ahar...@php.net I can't really see any way this could occur other than your server having a 64-bit install of Linux on it. What distribution is the server running, what does "uname -m" output, and what does configure say the host and target system types are? (Side note: the manual could admittedly be a bit clearer on this; although the fact integer size differs on different platforms is mentioned, it might be useful if the Integer Overflow section actually reiterated it. I'll see about updating it.) ------------------------------------------------------------------------ [2010-03-26 06:21:39] ssufficool at gmail dot com 64 bit ubuntu 10.04 PHP 5.3 SVN: int(2147483647) int(2147483648) 32 bit machine and OS PHP 5.2.10: int(2147483647) float(2147483648) ------------------------------------------------------------------------ [2010-03-11 19:05:31] cduncan at regatta dot com 64bit machine, 32bit OS. Also, wouldn't we expect a 64bit to return: int(2147483647) int(2147483648) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
