Please note:

1. |R is the only complete archimedian field. But any of its subfields is also archimedian.

2. The compatibility between the order and the multiplication operation:

   -One has the notion of "positive real numbers" (those numbers which are > 0)
   -|R satisfies one further property:  If a>b and c is positive, then ca>cb.

3. It is impossible to define an order in the field of complex numbers with all the mentioned properties.
