Yes, it is very interesting. I think it will be also useful in finance calculations.

Actually, on that note, would it be possible to allow an arbitrary scale factor instead of specifying a shift?  It ought to still be as efficient for power-of-two scales, on the assumption that compilers optimize multiplication and division by such constants...

I suppose that it would indeed be possible to use an arbitrary scale. If it is unclear if the compiler will optimize correctly, it should be straight forward to implement a scaling template with power-of-two as template specializations. Soren
