I've just reread my article "Zero Divided by Zero" in APL76
Proceedings, and it gives the case that 0%0 is 0. I still believe that
the quotient should be zero, for if it is one, the least common
multiple function fails, the distributivity of division over addition
fails; the arc (or phase, amplitude, argument or angle) fails; the
dyadic logarithm has a problem; as does the average of an empty
vector ; lastly, with the complex domain in view, zero is the only
symmetrical choice. It was persuasive to Ken Iverson, who saw its
truth, and saw to it that APL gave the zero value, as does J.
