I didn’t see exact floating points in Boost.
Are they already implemented?
The idea is pretty similar, I even considered the option of removing Qn and using just 3 integer types for the representation, but using same strategy of only change Qd when needed by an operation.
If there is someone already working on that datatype I will like to join the effort.
