These rules must apply to the subset of accounting situations that
involve exchange of funds.  However, pricing and costing of some items
regularly require a number of post-decimals beyond the '3 then round'
as you say is mandated.  An encforced rounding policy provided by a
Money subclass would require the programmer to invent work arounds for
these situations.  EIBTI   (Cool! I just learned what that means.)
