Yes. Lua supports.  Go to search
around for bitwise operation.
I used it before.  But forget where
I found the library.

Subject: Bitwise operations and binary number

Hi all,
I wonder if Lua supports binary number and bitwise operations or not.
I am play with an idea using a variable in binary to describe other
data structures.

for example

params_to_be_used{ a, b, c, d, e }
i_should_use = 10101   -- binary number
you_should_use = 10001 -- binary number

by having this,
I can simply using bitwise-AND, and find out what parammeter to be
used for different objects in order to avoid using too much memory
(using a array) or using too much computational time (using a lot of
if-elses).

I do aware there is alternative to archive this. But I am just
interested in whether binary number works in Lua or not.

Thanks!!
