# imaginary

From cppreference.com
< c‎ | numeric‎ | complex

Defined in header `<complex.h>` |  |
#define imaginary _Imaginary |  | (since C99)

This macro expands to a type specifier used to identify imaginary complex types. The macro is defined only if the implementation supports imaginary types.

| This section is incomplete Reason: on what condition? The standard seems unclear. Maybe when __STDC_IEC_559_COMPLEX__ is defined?

A program may undefine and perhaps then redefine the imaginary macro.
