A currency being a float type makes some sense. IIRC the Comp type was 
used to represent currency, a fixed point number with 5 decimals. This 
Comp type was defined and calculated in the numeric coprocessor (like 
all other floatingpoint types)
Therefore older versions of Delphi see this as float (iirc)
