#42812 [NEW]: integer value returned by php incorrect

From: laurent at polenord dot com Operating system: linux PHP version: 5.2.4 PHP Bug Type: Scripting Engine problem Bug description: integer value returned by php incorrect Description: ------------ infact the problem occurs on PHP 5.2.3 I want to simply return a float multiplied by a million, and force it to an integer value to avoid php returns int in weird format (2.9E+06 for example), and it doesn't return the correct value. This is very strange as it seems to occurs only on the '2.09' value : it's ok with 1.09 and 3.09, 2.19, 2.091 and 2.089, etc... Reproduce code: --------------- $cpc = '2.09'; echo $cpc * 1000000; // returns correct value : 2090000 echo "<br/>"; echo (int)($cpc * 1000000); // returns 2089999 !! echo "<br/>"; echo (int)($cpc * 1000 * 1000); // return correct value. Expected result: ---------------- 2090000 2090000 2090000 Actual result: -------------- 2090000 2089999 2090000 -- Edit bug report at http://bugs.php.net/?id=42812&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42812&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42812&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42812&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42812&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42812&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42812&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42812&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42812&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42812&r=support Expected behavior: http://bugs.php.net/fix.php?id=42812&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42812&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42812&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42812&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42812&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42812&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42812&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42812&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42812&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42812&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42812&r=mysqlcfg
