I agree with this wholeheartedly, and will start doing something about
it as soon as I can get the cycles.
The simplest solution is to change all dReal in the API to float, and
then add double-precision versions where it makes sense. ODE will
continue to use dReal internally.
It would be nice if there is also a way to separate the precision used
by the solver and the precision used by everything else. In my ideal
world, I would be able to use doubles for positions and floats for
