Thanks for bringing this to my attention.

I looked at this example
(http://jcc_7.tripod.com/d/tutor/currency.html) and you're exactly
right that using default
values is a much more elegant means of a solution. In fact, many
aspects of D have changed/improved since I wrote this example. For
instance, toString didn't use to handle doubles (thus the whole
toStringFromDouble function is obsolete and broken).

I'm phasing out that particular website (the pop-ups are really
driving me crazy), so I don't know if I'll update the code there, but
my newer tutorial efforts are hosted by dsource, such as this newly
updated version of the currency example:
http://www.dsource.org/projects/tutorials/wiki/CurrencyExample

(I guess I need to either add links to the new versions of the
examples on my tripod site or remove them completely.)
