I am very surprised by reading this. I must have missed a step in the advancement of mathematics.

The last time I was told about the properties of complex numbers field, there were no order relation available for it.

Therefore, no one may attempt a comparison between any complex number nor between a complex number and a real !

What's the new under the sky that have ordered the complex numbers ? That is surely a Vander full invention or an epic monster !


In this CAS software environment , what would be the result of comparing 4 + 7i and 14 + 0.3i ?
