How about IEEE 754 reals? They're really "scientific notation". There
has been a tremendous amount of work on them by William Kahan and
others and now are the standard for the numerical analysis world and
computers. Since this is the basics for computation, I'd propose that
they can be tightened up even more to suit constructivist purposes.
