| Description: | Converts the real part of a double complex argument to double precision type. This specific function has no generic function associated with it. It must not be passed as an actual argument. | ||
| Class: | Elemental function; Specific | ||
| Arguments: | A must be of type double complex (COMPLEX(8) or COMPLEX*16). | ||
| Results: | The result type is double precision real (REAL(8) or REAL*8). | ||
Examples
