Its not really a problem I was just wondering if the argument for any negative real number but no imaginary part was always = to pi?

ie -1, -2,-3, -0.65.... is the arg(z)=pi for all these cases

if so im guessing for positive real numbers with no imaginary part then Arg(z)=0

and likewise for imaginary numbers with no real parts then Arg(z)= pi/2 and -pi/2 respectively.

Thanks
