Call me a cynic or a curmudgeon as you prefer, but the future of new
users who would give so little thought and study to the tools they
are using as to find this a problem more than once, is to not use
shells at all.

It *is* probably less than ideal that "zcalc -f" is not the default
for the actual calculator utility; but pretending that $(( ... )) could
ever be described "a calculator with no surprises or gotchas" regardless
of integer arithmetic, is misleading because it isn't a calculator and
trying to think of it that way is going to cause surprises and gotchas.
