roundf() is the appropriate function here. The older MS crt headers
don't have the *round*() functions, but VS 2013 headers seem to have
them (according MSDN).
I propose adding them inside some #ifdef, instead of reimplementing them
in different places.

For the other functions: strange coding style. Is this taken from wine?
