>> You never use floating point operations in digital signal processing if you can get away with integers, because integer operations are so much cheaper and because the result is always more precise.

On Nvidia GPUs (the GPU in the machine), integer ops are second class citizens. The GPU architecture is optimized for floating point operations, and they do it extremely well. Using integers instead of floating point is not very advantageous. AMD GPUs are a different story however.
