    Nope. Note that -1 and +1 are both odd numbers. +2 and -2 are both even numbers.

    So the +/- sign doesn't matter?

    How about the last one? (3/2) and (7/2) are neither odd nor even.

    Think about it and you'll get it. Remember Euler's formula.

     exp(j\theta)=\cos(\theta)+j \sin (\theta)
