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。5 t6 s+ x1 l1 N9 p# |. W
So if want to compare these two numbers, it should compare there magnitude.
0 b: \! l1 T% A( T6 X1. x -> 0+0i
$ a2 b+ ?! j% I2. y -> 0+1i
5 G/ k5 c# x0 z

So, the magnitude of y >x |
