As x is a pure real number, but y only with imaginary part.
, L" c' d3 @/ l8 M6 x' ]So if want to compare these two numbers, it should compare there magnitude.tvb now,tvbnow,bttvb/ y: ~: ]1 j7 f9 k& V- U

Magnitude of x is |√(0^2 +0^2)| = 0tvb now,tvbnow,bttvb3 R5 E3 T* s4 Y# a! m2 r+ ?0 u
Magnitude of y is |√(0^2+1^2)| = 1
