As x is a pure real number, but y only with imaginary part.5.39.217.76; I4 {, {& V4 t# p
So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb8 X0 v0 D/ h! U7 x |3 Y4 a

Magnitude of x is |√(0^2 +0^2)| = 08 Y/ c6 {# m# [( m% _
Magnitude of y is |√(0^2+1^2)| = 1公仔箱論壇/ t4 [8 _) C5 Z7 m7 @3 p. J
