Re: Suggestions for hardware implementation
I am not sure if I understand your question correctly or not. The midpoint-radius representation of an interval can be considered as Cartisian representation. If we use x- and y-axis to represent midpoint and radius, respectfully, then a point in the upper-half plane specifies an interval. But, I am not sure if this can be helpful to the hardware vendors or not.

a random (maybe dummy) thought about hardware implementation: is it
possible to have hardware instructions that would be helpful both for
interval arithmetic (for the [lo, hi] representation) and for complex
floating-point arithmetic (for the cartesian representation)? If so,
this would increase the impact of such instructions, and maybe help to
convince the hardware vendors.
