As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb8 k1 H+ V6 P' z7 M- q: Z# M) }
So if want to compare these two numbers, it should compare there magnitude.* O4 h3 E3 \3 B* p

2. y -> 0+1i公仔箱論壇 U# b3 C, Q4 d0 M

Magnitude of x is |√(0^2 +0^2)| = 0. O6 @, u' ~7 C
Magnitude of y is |√(0^2+1^2)| = 1
