does anyone know how to rewrite this statement to a switch/case statement? thanks

n=input('Please enter a positive or negative integer: ');

if n < -2 n > 5

   disp(n/2)
else
    if n <= 3
        if n >= 0
            disp(floor(n/2))
        else
            disp(ceil(n))
        end
    else
        disp(1)
    end
end
