I'm sure you can manage that possibility better than I
can, now that you're taking it into account, but for
novices among us I'd like to mention that something
along the lines of the following statement can catch
the problem before it occurs:
assert. allDenominators ~: 0
I am particularly fond of J's assert. structure.
However, it requires explicit definition and thus may
run against some compositional and performance
considerations.
If there are fairly general solutions that have
developed for trapping division-by-zero other than
this, they might be worth publicizing.
