band( first, second )
Calculates the bitwise and of two numbers.
The first number.

The second number.

Superseded by & operator

The & operator added in 0.2.0 performs the same function as band() and is now the recommended way to do bitwise and, as it uses fewer tokens, costs fewer cycles at runtime, and runs on the real host CPU much more efficiently. Simply replace band(a,b) with a&b.


--     0x7 = 0111 binary
-- and 0xd = 1101 binary
-- -------
--     0x5 = 0101 binary
print(band(0x7, 0xd))  -- 5

print(0x7 & 0xd)       -- preferred method
