As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb( Z/ h- W4 J7 p B" J. U
So if want to compare these two numbers, it should compare there magnitude.www2.tvboxnow.com6 P/ E }+ M w" r4 \
1. x -> 0+0i! _& G, i) m. X% e7 J5 M( b5 ^
2. y -> 0+1i公仔箱論壇( E9 L* ]0 {) {8 N8 T, B

Magnitude of x is |√(0^2 +0^2)| = 0公仔箱論壇6 _; ~8 K, d" T* G
Magnitude of y is |√(0^2+1^2)| = 1

So, the magnitude of y >x |
