As x is a pure real number, but y only with imaginary part.
- {; O2 p5 x3 }* x# H' _公仔箱論壇So if want to compare these two numbers, it should compare there magnitude.5.39.217.763 }( ]' ?5 k, z, H

Magnitude of x is |√(0^2 +0^2)| = 05.39.217.761 q- J' G5 }0 y, t2 w& X9 ^
Magnitude of y is |√(0^2+1^2)| = 1

So, the magnitude of y >x |
