As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb* \" w+ o! p$ M$ ]
So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb: p4 ]1 N: j1 M+ o
1. x -> 0+0i* t6 d* H' z/ c$ X
2. y -> 0+1i
0 V; G l) `5 B5 w( y, |公仔箱論壇tvb now,tvbnow,bttvb. {5 ?: H0 M5 B7 O1 }: |; w
Magnitude of x is |√(0^2 +0^2)| = 0# U: I/ a$ W6 w! Y
Magnitude of y is |√(0^2+1^2)| = 1
4 a8 f Q$ x g% e6 @2 @tvb now,tvbnow,bttvb* F# V" b0 V) g
So, the magnitude of y >x |
