represents the domain of complex numbers, as in x∈Complexes.
- x∈Complexes evaluates immediately only if x is a numeric quantity.
- Simplify[expr∈Complexes] can be used to try to determine whether an expression corresponds to a complex number.
- The domain of real numbers is taken to be a subset of the domain of complex numbers.
- Complexes is output in StandardForm or TraditionalForm as . This typeset form can be input using comps.
