Wrong Tax calculation on HHVM

[ju2kr]

I'm running Magento 1.9.1.0 at HHVM 3.14.4

I added hhvm.enable_zend_sorting = 1 to /etc/hhvm/php.ini file and /etc/hhvm/server.ini, but the tax calculation is actually wrong.

34,90*0,07 = 2,429 and not 2,28 like Magento show it.

Has anyone an idea how I can solve my problem?
