Implementing a BCD math library isn't difficult.  It certainly would be 
slower than using native INTs and FLOATs but not devastatingly so.

You can use INTs as Jerry suggests and pretend that decimals don't exist 
except for display purposes.  So, for example, $1,524.79 would be stored 
as 1524790 which gives you three places of decimal precision (mils).
