Theorem cnfldle 14605

Description: The ordering of the field of complex numbers. Note that this is not actually an ordering on ℂ, but we put it in the structure anyway because restricting to ℝ does not affect this component, so that (ℂ_fld ↾_s ℝ) is an ordered field even though ℂ_fld itself is not.
