Theorem cnfldle 14827
Description: The ordering of the field of complex numbers. Note that this is not actually an ordering on  CC, but we put it in the structure anyway because restricting to  RR does not affect this component, so that  (flds  RR ) is an ordered field even though ℂfld itself is not. (Contributed by Mario Carneiro, 14-Aug-2015.) (Revised by Mario Carneiro, 6-Oct-2015.) (Revised by Thierry Arnoux, 17-Dec-2017.) Revise df-cnfld 14817. (Revised by GG, 31-Mar-2025.)
