As x is a pure real number, but y only with imaginary part.
4 ]1 P% K1 `9 T H% x0 X2 i' D" Z# D5.39.217.76So if want to compare these two numbers, it should compare there magnitude.) O+ j. ~- k- [" d

Magnitude of x is |√(0^2 +0^2)| = 04 v$ Y( P7 `7 _0 G" f# Q
Magnitude of y is |√(0^2+1^2)| = 1公仔箱論壇- r: A4 X/ A- u. E3 I) B
' Y* e0 `' K/ E: t# z- xSo, the magnitude of y >x |
