Obviously but this does not answer anything. You expect an int or a float, hence, you need to be prepared to handle floats. Your 7 example is the best illustration. You need to handle those situations in your script with the appropriate strategy for your domain (rounding, truncation, floor, ...). -- Richard "Fleshgrinder" Fussenegger -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
