I'm looking for an object or a simple abstraction to decode the bit values of a integer ( Ex: 5 = 101, so bit 0 = 1, bit 1 = 0, bit 2 = 1). If it doesn't exist, I can program a simple external.

Interesting solution, but I need to get the values of specific bits, not a "stream of bits". I found a good solution (attached). Sleep helps sometimes...

i've had a similar object kicking around in my library for a while, i also have a similar object for recombining bits.
attached.

it's also possible to create an object that's using bitwise AND operations:
such as:
inlet |______________________.. | | .. & N1 & N2 .. | | .. == N1 == N2 .. | | .. outlet outlet
with Nx=1,2,4,8,16,32,64...
it should work similar to pix abstraction, but i suppose that's cheaper ;-)
and it's easyer if you are only looking for a single bit...
btw, why isn't it allowed to create an expr like: expr ( ( $f1 & (2^$f2) ) == 2^$f2)

Guess I can't stop promoting k_cext:
[ k_cext 1 16; int i; RANGE(i, 0, 16) BEGIN; . O(i, (I(0) & (1<<i))>0); ENDRANGE ]

I've never seen (or heard of) such an object, but you could use PD's binary bitwise operators &, |, ~ for this purpose, giving them suitable constants (2**n) as arguments / right-inlet inputs.
If you need more bits than will fit into a single t_float (here on linux seems to be ca. 30 bits), it might be easier to program an external which handles lists of floats as long bit-vectors...
