    The HDC itself is dimensionless. It merely provides an interface between you and the device driver. The actual physical surface is a bitmap. So create one of that size and select it into the device context. But remember that screen contexts cannot select a bitmap ( their bitmap is the one you're looking at right now ).
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }
