From: Operating system: Windows PHP version: 5.3.4 Package: Math related Bug Type: Bug Bug description:PHP hangs on numeric value 2.2250738585072011e-308
Description: ------------ If I assign the value 2.2250738585072011e-308 to a variable, e.g. $d = 2.2250738585072011e-308, PHP hangs (loops). I am using PHP 5.3.1 XAMPP 1.7.3 on Windows. 2.2250738585072011e-308 represents the largest subnormal double-precision floating-point number, 0.1111111111111111111111111111111111111111111111111111 x 2^-1022. Interestingly, nearby decimal literals 2.2250738585072008e-308, 2.2250738585072009e-308, 2.2250738585072010e-308 and 2.2250738585072012e-308 -- which all convert to the same floating-point value -- do not cause this problem. Test script: --------------- <?php $d = 2.2250738585072011e-308; ?> Expected result: ---------------- No Hang. Actual result: -------------- Hang. -- Edit bug report at http://bugs.php.net/bug.php?id=53632&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53632&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53632&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53632&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53632&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53632&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53632&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53632&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53632&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53632&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53632&r=support Expected behavior: http://bugs.php.net/fix.php?id=53632&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53632&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53632&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53632&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53632&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53632&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53632&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53632&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53632&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53632&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53632&r=mysqlcfg
