Hi spam.me,

We had not heard of this technique before nor can find it in NVIDIA's CUDA programming guide (version 2.1). We do see where they will 'demote' 64-bit to 32-bits but I don't think this what you want.

In any event, I don't think it something we would support given new NVIDIA cards do support double precision.

Dear mkcolg,

sorry for the confusion. The mention stuff was not part of CUDA but of ATI Stream. If you're interested, please take a look in [1] on page 3-36/122 Double-Precision Arithmetic.

Have a nice day!
