Its my understanding that MONEY is deprecated that you really should
store money values as NUMERIC instead.
a wild guess says thats some variant on NUMERIC, which is stored in
base 10000 as a series of 16 bit integers, with a fuixed point fraction.
why would you convert money to floating point? $0.10 in binary floating
point is a repeating fraction which can't be represented exactly
btw, are you sure your value isn't $51.20 ? 0x1400 is 5120 decimal.
