From: edelmar at ditech dot com dot br Operating system: Win XP PHP version: 4.3.11 PHP Bug Type: *Math Functions Bug description: floor does not work with some integers as argument
Description: ------------ Using PHP Version 4.3.11 on Windows xp (my development machine). I believe this behavior of floor function is a bug. The number 7560 passed to it is an integer and would not be changed by floor. I am using 100 times number because PHP has no function like 'truncate'. I want 2 decimals and there is no way to do it with regular functions. Its like 7560 has some special properties because this error does not happens with a lot of other numbers. Thank you. Reproduce code: --------------- echo (75.6 * 100).'<br>'; // prints 7560 - OK echo intval(75.6 * 100).'<br>'; // prints 7559 - ? echo (int)(75.6 * 100).'<br>'; // prints 7559 - ? echo floor(75.6 * 100).'<br>'; // prints 7559 - ? echo ceil(75.6 * 100).'<br>'; // prints 7560 - OK echo round(75.6 * 100).'<br>'; // prints 7560 - OK Expected result: ---------------- 7560 7560 7560 7560 7560 7560 Actual result: -------------- 7560 7559 7559 7559 7560 7560 -- Edit bug report at http://bugs.php.net/?id=33009&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33009&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33009&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33009&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33009&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33009&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33009&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33009&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33009&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33009&r=support Expected behavior: http://bugs.php.net/fix.php?id=33009&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33009&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33009&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33009&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33009&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33009&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33009&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33009&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33009&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33009&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33009&r=mysqlcfg
