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。& H f0 m1 W2 }9 \- p6 k9 ?* S
So if want to compare these two numbers, it should compare there magnitude.

Magnitude of x is |√(0^2 +0^2)| = 01 P$ M& [+ m5 A& Q
Magnitude of y is |√(0^2+1^2)| = 1' ^0 o0 _/ [) B5 A; M

So, the magnitude of y >x |
