As x is a pure real number, but y only with imaginary part.
7 ] y, `1 ]( y7 f, S( B! ^" qwww2.tvboxnow.comSo if want to compare these two numbers, it should compare there magnitude.公仔箱論壇( G8 V5 I# C# m X$ x$ {

Magnitude of x is |√(0^2 +0^2)| = 03 G" T+ p: ~* ~( A) ^; t$ P
Magnitude of y is |√(0^2+1^2)| = 1( j- ]/ e* s. N. S+ c8 [( `
