From: mr-russ at pws dot com dot au Operating system: Ubuntu Linux 8.04 PHP version: 5.2CVS-2008-05-02 (snap) PHP Bug Type: *General Issues Bug description: converting some doubles to strings yields trailing colon
Description: ------------ I expect any number, divided by 10 times itself, then converted to a string, to yield "0.1" In this release, sometimes I get "0.0:" (yes, that's 0.0 with a trailing colon character) I have tested on i386 and amd64. amd64 behaves as expected. i386 gives the invalid result. Original bug report by Brett Kiefer on Ubuntu Launchpad: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/218891 Reproduce code: --------------- <?php for ($d = 0.10; $d < 1; $d = $d + 0.1) print $d * 10 . " " . ($d / ($d * 10)) . "\n"; ?> Expected result: ---------------- 1 0.1 2 0.1 3 0.1 4 0.1 5 0.1 6 0.1 7 0.1 8 0.1 9 0.1 10 0.1 Actual result: -------------- 1 0.1 2 0.1 3 0.1 4 0.1 5 0.1 6 0.0: 7 0.0: 8 0.1 9 0.0: 10 0.1 -- Edit bug report at http://bugs.php.net/?id=44890&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=44890&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=44890&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=44890&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=44890&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=44890&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=44890&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=44890&r=needscript Try newer version: http://bugs.php.net/fix.php?id=44890&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=44890&r=support Expected behavior: http://bugs.php.net/fix.php?id=44890&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=44890&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=44890&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=44890&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=44890&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=44890&r=dst IIS Stability: http://bugs.php.net/fix.php?id=44890&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=44890&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=44890&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=44890&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=44890&r=mysqlcfg
