As x is a pure real number, but y only with imaginary part.TVBNOW 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。# h2 W! W5 @# g% [+ X* b
So if want to compare these two numbers, it should compare there magnitude.. |9 h6 {* C2 Y7 i- Y2 d! f
1. x -> 0+0i6 ]" x4 s- _. X' [7 i. W
2. y -> 0+1i

Magnitude of x is |√(0^2 +0^2)| = 07 s- L) y* F, E% P! D0 p$ F
Magnitude of y is |√(0^2+1^2)| = 1

So, the magnitude of y >x
