The floating point behaviour was changed in PHP 5.3, as in this RFC by Christian Seiler (cc'ed): http://wiki.php.net/rfc/rounding You can find where the zend_float.h file is included by a simple grep: C:\php\src\> grep -ri "zend_float" * Zend/zend_execute_API.c:#include "zend_float.h" Zend/zend_float.c:#include "zend_float.h" Zend/zend_float.h:/* $Id: zend_float.h 277398 2009-03-18 10:18:10Z dmitry $ */ Zend/zend_float.h:#ifndef ZEND_FLOAT_H Zend/zend_float.h:#define ZEND_FLOAT_H -- regrads, Kalle Sommer Nielsen ka...@php.net -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
