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.

Reproduce code:
---------------
var_dump(0.01 + 0.09)

Expected result:
----------------
float(0.1)

Actual result:
--------------
float(0.0:)
