As x is a pure real number, but y only with imaginary part.5.39.217.769 W4 x; H1 S! q+ V6 d
So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb6 z$ \% h6 g/ B: ?3 p
1. x -> 0+0i
$ ~: [" ?# G  H7 [1 A" s6 }& d5.39.217.762. y -> 0+1i, d& M8 F2 c7 D- \$ ]/ {4 w
