As x is a pure real number, but y only with imaginary part.2 _: C! I% a! P& g% O/ V& j- I0 L
So if want to compare these two numbers, it should compare there magnitude.公仔箱論壇: i* y! m% O( H! R; x1 N( v
1. x -> 0+0i
+ {, C; h5 J. |' f7 HTVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。2. y -> 0+1i
$ R0 a! @ q, ^* x/ _2 G8 |* W, _- K. d% F1 V# ~, r5 W
Magnitude of x is |√(0^2 +0^2)| = 0
0 g4 V; S* I& e: @5.39.217.77:8898Magnitude of y is |√(0^2+1^2)| = 1! K$ y. l/ P0 K ?% l' K9 ^0 i

So, the magnitude of y >x |
