comment Finding a “not-shortest” path between two vertices
My goodness, this really does work. I never used FindPath and am curious to get a sense of how it works.

comment Can Mathematica Handle Open Intervals? Interval complements?
I used Mathematica v.9 (or v. 8). I must have drawn everything "by hand". If I were to do it with v.10, I would use NumberLinePlot[{{-\[Infinity] < x < -2, -1 < x <= 1, 4 < x <= Pi^2}}, x] and so forth.

I assume that means that the empty region is indeed a region.

comment Real Numbers in the Wolfram Language
The folks from Wolfram Research may be able to answer whether MMA is 754 compliant or not. As regards your final question, it seems that no machine implementation will be able to handle all real numbers, so the problem boils down to what name(s) will be used to designate some subset of the reals that might correspond to finite decimals. Perhaps there ought to simply be some clearer way of distinguishing the form of a number (the data type) from the number domain it is presumably a member of. In principle, I would think it reasonable to reserve Real and Rational for domains, not data types. .

Yes. Good point. Inheritance would seem to allow for embedded classes.

@OleksandrR I would certainly welcome your contribution to the discussion base on your points in chat. I realize that this discussion will not lead Wolfram to change or add functions, but I find it enlightening nonetheless.

Michael E2, Unfortunately I have not been able to log in to the chat room. I even tried changing my password, to no avail.

comment How would I use sliders to manipulate the slope and intercept of a plane in a graphics 3d box while the cdf was running
You might start by drawing a single plane with Plot3D. From there you can identify, in your function, the parameters that you would like to vary. Each can then be associated with a slider.

comment Real Numbers in the Wolfram Language
Michael E2, I'm intrigued to hear (but have no reason to doubt) that mathematicians have several ways of looking at such basic objects as integers. My admittedly limited understanding was that such foundational issues had been resolved and agreed upon once and for all.
