First the creation of dollar strings
You can make a few functions called dollar and dollarComma and
dollarCommaSign, or some better names you think up. The first
simply uses round to round to two digits; it is for math. Use it
on the result of every every multiply involving money. For display
or output always use dollarComma and dollarCommaSign. The first
adds 0 to force to number, uses numberFormat and, say, "& empty" to
force to string and then adds the commas for multiples of $1,000.
The second takes that and adds $. You might want dollarComma to
throw if the arg is not a number.
If you want to make sure functions return money, insert the
appropriate function into your return commands. Comments about
numberFormat are only in one place.
The next I would do is ask how that 8 got there. Shouldn't that
process have put it into the form you want? (If you use the above
functions for display, it shouldn't matter though.)
Applying numberFormat to every return would require math functions
we write to have to set numberFormmat every time and would use up
cpu cycles for every return and for every use of functions.
