High precision floats on CUDA

Hope this hasn't already been asked, but... is there any simple way to get high precision floats (something lime 1024 bits precision) working on CUDA without having to code it from scratch? I'd need something very simple, and I need only operator + and *... is this possible?

CUDA Compute 1.3 and above cards will do double precision out of the box without you having to implement it yourself. Basically anything after GTX 280 and Quadro 5800. If you need more precision than that then you will have implement it yourself.
