TYPO3 Core

when clicking on a news item (uri+query string like: index.php?id=4&backPID=4&tt_news=1) php raises a fatal error:

Call to undefined function: float() in /var/www/typo3/typo3_src-3.7.0/t3lib/class.t3lib_cs.php on line 1500

replacing the float(phpversion()) in line 1500 t3lib/class.t3lib_cs.php with floatva(phpversion()) resolved the problem for me.

mod_php = 4.3.9
apache = 2.0.52
