My code is calculating 3D-DCT, for a large set of data.

It's running on GeForce 9400M, compute capability 1.1 (which does not support double precision as far as I know).

Is there a way to enable it, or to handle the values correctly?

    See njuffa's answer in stackoverflow.com/questions/6769881/… for a good answer (the gist is to use two floats to approximate a double) Commented Mar 27, 2013 at 18:25
