__device__ double nextafter ( double  x, double  y   ) Calculate the next representable double-precision floating-point value following x in the direction of y. For example, if y is greater than x, nextafter() returns the smallest representable number greater than x Returns: nextafter(, y) returns . Note: For accuracy information for this function see the CUDA C Programming Guide, Appendix C, Table C-2.
