#31026 [NEW]: Problem with type conversion

From: tobi at knmm dot de Operating system: Linux 2.6.8 (Debian sarge) PHP version: 4.3.9 PHP Bug Type: Variables related Bug description: Problem with type conversion Description: ------------ A very strange problem occurs on my webserver. If you run the provided code via http://knmm.de/bug.php a few times, in about 1 out of 10 times the second line of output is "$price is a double with value 34". This shows up randomly. Running the script on the commandline of the same machine doesn't show this behaviour. -- Tobi Reproduce code: --------------- $price = '34.90'; echo "\$price is a ".gettype($price)." with value $price\n"; settype($price,'double'); echo "\$price is a ".gettype($price)." with value $price\n"; (also available via http://knmm.de/bug.phps) Expected result: ---------------- $price is a string with value 34.90 $price is a double with value 34.9 Actual result: -------------- $price is a string with value 34.90 $price is a double with value 34 -- Edit bug report at http://bugs.php.net/?id=31026&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=31026&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=31026&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=31026&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=31026&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=31026&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=31026&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=31026&r=needscript Try newer version: http://bugs.php.net/fix.php?id=31026&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=31026&r=support Expected behavior: http://bugs.php.net/fix.php?id=31026&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=31026&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=31026&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=31026&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=31026&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=31026&r=dst IIS Stability: http://bugs.php.net/fix.php?id=31026&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=31026&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=31026&r=float MySQL Configuration Error: http://bugs.php.net/fix.php?id=31026&r=mysqlcfg
