#46376 [NEW]: var_dump(0.09 + 0.01); // float(0.0:)

From: s6urik at gmail dot com Operating system: Linux (Amazon EC2) PHP version: 5.2.6 PHP Bug Type: Scripting Engine problem Bug description: var_dump(0.09 + 0.01); // float(0.0:) Description: ------------ Result of expression "0.01 + 0.09" is "float(0.0:)", yes, zero dot zero colon. Though "0.1 * 0.1 + 0.9" returns "float(0.1)" as it should, so internally float looks to be stored correctly. This bug appears only in Amazon EC2 virtual hosting environment: Instance Type: Small Instance Kernel: Linux 2.6.21.7-2.fc8xen #1 SMP Fri Feb 15 12:39:36 EST 2008 i686 GNU/Linux Tested PHP versions: 5.2.4, 5.2.6 PHP 5.3.0alpha3-dev is not affected.
