This is why it is such a good idea to 'echo back' the input data as your
program sees it. There are all sorts of conversion and accuracy issues,
plus the fact that your program can never tell if the way it interprets
the numbers is the way that the user of the program intended.( I would
avoid anthromorphizing the software here, except that makes it even more
complicated to understand. The user may be a later edition of the
author, as in this case. But from the program's point of view, the
assumptions never changed...) If the percentage rate had been 'echoed'
as 0.02% you would have seen the mistate immediately--or at least sooner.
