Does MSVC have roundf? It's defined in exactly the same standards as rintf
(C99, POSIX).

In any case, it has most of the same problems as (int)(x + 0.5) has
(I assume you meant int or long, not unsigned char; the latter would surely
be a disaster); it needs a slow round-with-truncate, and it has a rounding
bias, so it rounds e.g. 0.5 wrong. It's somewhat better with negative
numbers, though.
