As x is a pure real number, but y only with imaginary part.tvb now,tvbnow,bttvb) ]/ }2 m' P6 U; Y3 l; a y4 A9 v
So if want to compare these two numbers, it should compare there magnitude.! o' m8 E" u, X/ M# Z% G

Magnitude of x is |√(0^2 +0^2)| = 0
1 {1 b2 }1 M4 F% W5.39.217.76Magnitude of y is |√(0^2+1^2)| = 1

% b* i% c* A: ^7 D5.39.217.76So, the magnitude of y >x |
