As x is a pure real number, but y only with imaginary part.
$ p# X. ]$ u, B$ oSo if want to compare these two numbers, it should compare there magnitude.

5 t! b! \: W2 s; u' T/ V: ^- |; c
Magnitude of x is |√(0^2 +0^2)| = 0
7 T% K) J/ R( A9 `* \Magnitude of y is |√(0^2+1^2)| = 1os.tvboxnow.com5 C6 b7 U' [' f! \9 r) ~, ]. F& i5 k
