Is there a function for Converting a Decimal into BINARY ?

Hi Guys,

Searching the net didn't give me much clues as to how to convert a Decimal
number into BINARY.


Eg:
I have a datatype in the DB which needs to be converted.

DEC = 192
BINARY = 11000000

DEC = 197
BINARY = 11000101

Which I then need to break down into pairs to do calculations on

11 : 00 : 00 : 00
11 : 00 : 01 : 01

Some of the solutions I've seen on the Internet is based on VB and mainly
userland apps, I would like to do the conversion within PG itself.

Thanks
