Here is the script I can only use integers, I was wondering if there is anyway to modify the script so I can use floats with MoveMouseRelative.

EnablePrimaryMouseButtonEvents  (true);
function OnEvent(event,arg)
    if IsKeyLockOn("ScrollLock")then
        if IsMouseButtonPressed(3)then
            repeat
                if IsMouseButtonPressed(1) then
                    repeat
                        MoveMouseRelative(0,2)
                        Sleep(10)
                    until not IsMouseButtonPressed(1)
                end
            until not IsMouseButtonPressed(3)
        end
    end
end
