The first attempt in this code was to 'type' output as a number (float/int)
so that when it was assigned the value of input, it would be represented as
a number.  The problem lies in the fact that parseFloat is internally called
(I assume) when you try to say "output = 1 * (0 + input)".  But all you
wanted was to be able to write() the result (instead of return a
non-string), and my function does that.

BTW.. more on this available at JavaScript 411.
