From: rbro at hotmail dot com Operating system: Linux PHP version: 5CVS-2007-10-05 (snap) PHP Bug Type: BC math related Bug description: bcmath incorrect results / number format
Description: ------------ When adding certain floating point numbers together using bcadd (or using the other bcmath functions), I'm receiving invalid results at times depending on the inputs. It appears that with recent PHP releases, PHP is expressing certain floating point numbers in scientific notation which bcmath is not correctly handling. Using my example below, PHP is expressing the number 1200000.00 as 1.2E+6 which is causing incorrect results from bcadd. Reproduce code: --------------- <?php bcscale(2); echo bcadd(1200000, 1)."\n"; echo bcadd(1200000.00, 1)."\n"; Expected result: ---------------- 1200001.00 1200001.00 Actual result: -------------- 1200001.00 1.00 -- Edit bug report at http://bugs.php.net/?id=42871&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42871&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42871&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42871&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42871&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42871&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42871&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42871&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42871&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42871&r=support Expected behavior: http://bugs.php.net/fix.php?id=42871&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42871&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42871&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42871&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42871&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42871&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42871&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42871&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42871&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42871&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42871&r=mysqlcfg
