Bitwise Operators

Lua 5.3 introduced the ability to use true integers, and with it bitwise operations. These operations are invoked similar to the addition operation, except that Lua will try a metamethod if any operand is neither an integer nor a value coercible to an integer.

__band - (Lua 5.3) the bitwise AND (&) operation.
__bor - (Lua 5.3) the bitwise OR (|) operation.
__bxor - (Lua 5.3) the bitwise exclusive OR (binary ~) operation.
__bnot - (Lua 5.3) the bitwise NOT (unary ~) operation.
__bshl - (Lua 5.3) the bitwise left shift (<<) operation.
__bshr - (Lua 5.3) the bitwise right shift (>>) operation.
