Can we do Bitwise Operations, or do i need a pseudo function to iterate through options?

I'd like to do something similar to the following, but with fewer If statements, if you get where I am going with this; through research it appears Roblox Lua doesn't allow for Lua 5.3 bitwise operations?

local N = 1					-- Bitwise enumerators for wall placement
local S = 2
local E = 4
local W = 8

if bitValue == N or bitValue == N + S .......... then  -- North Wall
	InsertWallPart(parent, x, _posY or defaultFloorY, z, N)
end
if bitValue == W then  -- West Wall
	InsertWallPart(parent, x, _posY or defaultFloorY, z, W)
end
if bitValue == S then 
	InsertWallPart(parent, x, _posY or defaultFloorY, z, S)
end
