As x is a pure real number, but y only with imaginary part.5.39.217.76( j& ]* U8 b/ u/ s
So if want to compare these two numbers, it should compare there magnitude.; K# q% c* F& l
1. x -> 0+0i

Magnitude of x is |√(0^2 +0^2)| = 0TVBNOW 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。# ~; S; D+ F1 d5 C$ T
Magnitude of y is |√(0^2+1^2)| = 1: O, Y& M9 e5 r
