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
Eg:
I have a datatype in the DB which needs to be converted.DEC = 192
BINARY = 11000000
How about this....
gwmdb=> select 192::bit(16);
bit
------------------
0000000011000000
(1 row)
Hope that helps

well, a decimal number is a fixed point number stored in a modified BCD
format, which optionally can contain a decimal fractional component.
you likely would want to convert it to a INTEGER or BIGINT first, then
cats it to BIT(n) where N is the number of bits you want.
