Dealing with error values (such as INF, divzero, etc.) does not necessarily
preclude one from "mathematicality." I seem to recall that the folks working
on dataflow architectures rigorously defined the math for propogating error
values so that traps, etc., would not be necessary. I don't recall the author
but I believe the title of the paper was Error Values in Val.
