This math scares me

Visual Basic (and products that embed it) does have a Currency data type,
but it is a (clever) hack.  Externally, it looks like a fixed-point value
wherein four decimal places can be stored and manipulated exactly.
Internally, it is just a double precision floating point number, scaled by
10,000.  So, if you do this:

  Dim x As Currency
  x = 1.23

x will actually contain the double precision value 12300.0.  The conversion
routines do the scaling automatically where required.
