As x is a pure real number, but y only with imaginary part.
, H) M% g" n6 e8 c$ z# k& R公仔箱論壇So if want to compare these two numbers, it should compare there magnitude.公仔箱論壇 }5 W- x @. h2 z0 b/ E' W4 z
1. x -> 0+0i

Magnitude of x is |√(0^2 +0^2)| = 0/ i- a0 k" @+ ~! G6 W. w
Magnitude of y is |√(0^2+1^2)| = 1tvb now,tvbnow,bttvb: f) a6 D+ s( _% b( x. \; F; q
