As x is a pure real number, but y only with imaginary part.公仔箱論壇) S6 J: h% s# i2 ?) R
So if want to compare these two numbers, it should compare there magnitude.5.39.217.767 a* c3 K$ f( ]! w& y; r

Magnitude of x is |√(0^2 +0^2)| = 05.39.217.76% y1 t+ s6 p. V4 }7 v, D" f
Magnitude of y is |√(0^2+1^2)| = 16 ~1 j8 i; S3 d8 O/ D* u5 T

So, the magnitude of y >x |
