Just never cast floats to integers directly, use round() instead, this will clear the float-specific inaccuracy: $v = (int) round((0.7 + 0.1) * 10); Your code is in fact the same as this: $v = (int) floor((0.7 + 0.1) * 10); and floor(7.99999999999999) is still 7. And to follow Thomas' reply: yes, this is a PHP thing, not a symfony thing.
