As x is a pure real number, but y only with imaginary part.- c) ~* o2 N, |: s/ L0 l& S) a
So if want to compare these two numbers, it should compare there magnitude.
3 i4 h1 R$ ~7 J s) V9 u5 x+ Rtvb now,tvbnow,bttvb1. x -> 0+0i

Magnitude of x is |√(0^2 +0^2)| = 0公仔箱論壇/ l0 l0 n$ b' ? b" X5 Z2 G% m' B
Magnitude of y is |√(0^2+1^2)| = 1) B( ~/ M' z* h" u) u
3 i, W2 l4 a8 l4 S+ S3 jSo, the magnitude of y >x |
