The following compiles fine for me with MSVC10 and boost 1.47.0:

#include <boost/math/special_functions/round.hpp>
 
const int TILEWIDTH = 5;
const int X = 0;
const int Y = 1;
 
double translation[2] = {1.0, 1.0};
 
int main()
{
    translation[X] = boost::math::round( (translation[X]/TILEWIDTH) ) * TILEWIDTH;
    translation[Y] = boost::math::round( (translation[Y]/TILEWIDTH) ) * TILEWIDTH;
}

Could you provide a complete example that fails to compile for you?

Thanks,
Nate
