ID: 54973 Comment by: bphelpsen at gmail dot com Reported by: bphelpsen at gmail dot com Summary: SimpleXML casts intergers wrong. Status: Bogus Type: Bug Package: SimpleXML related Operating System: Linux PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Then why do I get different results when I run this code: <?php echo "214748364800" / 1024 / 1024 / 1024; ?> than when I run the example code. Shouldn't they return the same value? Here is an example, with the same results as my local test: http://codepad.org/KICl3xHw Previous Comments: ------------------------------------------------------------------------ [2011-06-02 20:00:54] il...@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This has nothing to do with SimpleXML, but rather the fact that a numeric string in PHP by default would converted to an integer. ------------------------------------------------------------------------ [2011-06-01 22:18:27] bphelpsen at gmail dot com Description: ------------ When an XML node value is an integer SimpleXML always casts it to an int, even if its a float or double. Test script: --------------- <?php $xml = simplexml_load_string("<xml><number>214748364800</number></xml>"); echo $xml->number . "\n"; // the proper number $int = $xml->number / 1024 / 1024 / 1024; // initial cast to an int causes problems echo $int . "\n"; $double = (double) $xml->number / 1024 / 1024 / 1024; // hard cast to a double fixes it echo $double . "\n"; ?> Expected result: ---------------- 214748364800 200 200 Actual result: -------------- 214748364800 1.9999999990687 200 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54973&edit=1
