			-- Note: there are no bit shift. Use those Lua functions instead for 24 bits bitshift
			-- 24 bits because only the 24 bits of the mantissa can be easily used in a 32 bit float
			-- bitshift functions (<<, >> equivalent)

			-- shift left
			local function lsh(value,shift)
			return (value*(2^shift)) % 2^24

			-- shift right
			local function rsh(value,shift)
			return math.floor(value/2^shift) % 2^24
