DOUBLE COMPLEX § 77The DOUBLE COMPLEX statement establishes the data type of a variable by explicitly attachingthe name of a variable to a double complex data type. This overrides the implication of data typingby the initial letter of a symbolic name.SyntaxThe syntax for DOUBLE COMPLEX has two forms, a standard Fortran 90/95 entity based form,and the PGI extended form. This section describes both syntax forms.DOUBLE COMPLEX [, attribute-list ::] entity-listattribute-listentity-listSyntax Extensionis the list of attributes for the double complex variable.is the list of defined entities.DOUBLE COMPLEX name [/clist/] [, name] [/clist/]...nameclistis the symbolic name of a variable, array, or an array declarator (see theDIMENSION statement for an explanation of array declarators).is a list of constants that initialize the data, as in a DATA statement.DescriptionType declaration statements may be used to dimension arrays explicitly in the same way as theDIMENSION statement. Type declaration statements must not be labeled. Note: The data type of asymbol may be explicitly declared only once. It is established by type declaration statement,IMPLICIT statement or by predefined typing rules. Explicit declaration of a type overrides anyimplicit declaration. An IMPLICIT statement overrides predefined typing rules.The default size of a DOUBLE COMPLEX variable is 16 bytes. With the -r8 option, the defaultsize of a DOUBLE COMPLEX variable is also 16 bytes.ExamplesDOUBLE COMPLEX CURRENT, NEXT§78 Chapter 3
