I need a reference to a paper that says if a problem is easy to solve then it is also easy to solve on a machine in which every piece of data is a rational number to any precision and $+,-,\cdot, \div$ are all $O(1)$ operations. With possibly more operations allowed, whatever they think is appropriate. Seems obvious though. If I wrote a paper, would I have to say anything more than that?
