#41344 [Opn->Bgs]: Error returning long values in the headers

ID: 41344 Updated by: tony2001@php.net Reported By: zeta2ste2000 at yahoo dot it -Status: Open +Status: Bogus Bug Type: SOAP related Operating System: HP-UX 11.11 PHP Version: 5.2.2 New Comment: Floating point values have a limited precision. Hence a value might not have the same string representation after any processing. That also includes writing a floating point value in your script and directly printing it without any mathematical operations. If you would like to know more about "floats" and what IEEE 754 is read this: http://docs.sun.com/source/806-3568/ncg_goldberg.html Thank you for your interest in PHP.

The original sent value can't be retrieved and the returned one is different. Reproduce code: --------------- A Java server sends a sessionID in the header with the following value : 339051398236687110 This is the client code : $soapclient->__soapCall('beginSession',$parameters, null, null, $header); echo $header["sessionID"]; // returns 3.3905139823669E+17 , an // invalid value for the next call // and with less digits than required $strNum = number_format($header["sessionID"], 0, "", ""); echo $strNum; // returns the rounded value // 339051398236687050 , that is // different from the original // 339051398236687110 Expected result: ---------------- The header has to contain 339051398236687110 Actual result: -------------- The header contain 3.3905139823669E+17 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41344&edit=1
