As x is a pure real number, but y only with imaginary part.5.39.217.76( f" a4 _: A \+ C( a' o( ^
So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb9 _0 T N5 e$ k: a7 b/ l0 }4 d

Magnitude of x is |√(0^2 +0^2)| = 0
$ a& n, k" I1 M" V: I; P+ QMagnitude of y is |√(0^2+1^2)| = 1
