I'm trying to read "money" field using PQgetvalue (PostgreSQL 8.3.7). The function returns 9 bytes, smth like 0h 0h 0h 0h 0h 0h 14h 0h 0h, for the value '$50.2'. I could not find description anywhere on how to convert the binary data into, for example, a double precision number. Would you please help me find a method of converting binary "money" data into a double precision?

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.
