This functions performs an arithmetic shift on the integer value by integer n positions. In an arithmetic shift, zeros are shifted in to replace the discarded bits. In a right arithmetic shift, the sign bit is shifted in on the left, thus preserving the sign of the operand. See Bitwise operation for more details.

This example adds the clientside command/arshift [value] [positions = 1], which will print the result from the functionbitArShift.

function getNumberAsBitString(value)
    if type(value) ~= 'number' then
        return false
    else
        local binary = ''

        for field = 31, 0, -1 do
            binary = binary .. bitExtract(value, field)

            if field % 4 == 0 then
                binary = binary ..' '
            end
        end

        return binary
    end
end

addCommandHandler('arshift',
    function (command, value, positions)
        if type(value) ~= 'string' or value:len() == 0 then
            return outputChatBox('* Syntax: /arshift [value] [positions = 1]')
        end

        if type(positions) ~= 'string' or positions:len() == 0 then
            positions = 1
        end

        local result = bitArShift(tonumber(value), tonumber(positions))
        local binary = getNumberAsBitString(result)

        outputChatBox('* Decimal: '.. result ..', Binary: '.. binary)
