From: zuallauz at gmail dot com Operating system: Ubuntu 12.04 PHP version: 5.4.3 Package: *General Issues Bug Type: Bug Bug description:5.4.3 regression, converting from float to int gives incorrect output
Description: ------------ Ok this code correctly works on 5.3.3 but I have since upgraded to 5.4.3 and it now incorrectly casts the float to an integer. It occurs when converting the output from the log() function to an integer. It should be a simple float to int conversion. However in the current stable PHP it outputs the wrong integer for no apparent reason. I have compiled PHP 5.4.3 release with the following if that helps: ./configure --with-zlib --with-gd --with-jpeg-dir --with-png-dir --enable-gd-native-ttf --with-freetype-dir --enable-bcmath --enable-sockets --with-openssl --with-pdo-mysql=mysqlnd --with-mysql-sock=/var/run/mysqld/mysqld.sock --enable-mbstring --enable-mbregex --with-curl --with-apxs2=/usr/local/apache2/bin/apxs --with-config-file-path=/usr/local/apache2/conf I consider this a critical bug so please fix ASAP. Test script: --------------- $logarithm = log(8, 2); var_dump($logarithm); $int = (int) $logarithm; var_dump($int); Expected result: ---------------- Expected output as it is in PHP 5.3.3: float(3) int(3) Actual result: -------------- Actual output in PHP 5.4.3: float(3) int(2) -- Edit bug report at https://bugs.php.net/bug.php?id=62240&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62240&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62240&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62240&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62240&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62240&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62240&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62240&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62240&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62240&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62240&r=support Expected behavior: https://bugs.php.net/fix.php?id=62240&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62240&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62240&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62240&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62240&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62240&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62240&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62240&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62240&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62240&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62240&r=mysqlcfg
