How can i call intrinsic CUDA math functions?

I am using visual studio 2013. Used MFC for the UI and did some heavy calculations in CUDA. I am trying to speed up the process, so want to change some functions to intrinsics. However error message appears that it says not defined.

I think it is something to do with the CUDACC because device_functions.h says if CUDACC need to be defined to use the whole functions.

__device__ float cuint2float(int nInput)
{
    return __int2float_rn(nInput);
}

How can I enable this option?

It was just a intellisense error. I could execute the program.
