A FAQ Number formatting routine should give correct results for all
values of the type Number.  Users who have confidence (often misplaced)
that some values will not occur can simplify the code if they need to.

For pedagogical reasons, maybe the FAQ answer should include an initial
test, commented out, that the input is indeed a Number.  With your
(original) code,   formatNumber2(formatNumber2)   returns NaN, which is
not ideal.  The result of a function call should never be misleading.

My Web site includes good, indifferent, and bad formatters.
