Chapter 10330
DOUBLE COMPLEX (extension)
Declares entities of type double complex.
Syntax
DOUBLE COMPLEX [ [,
attrib-list
] ::]
entity-list
attrib-list
is a list of one or more of the following attributes, separated by commas:
If
attrib-list
is present, it must be followed by the double colon. For
information about individual attributes, see the corresponding statement in
this chapter.
entity-list
is a list of entities, separated by commas. Each entity takes the form:
name
[(
array-spec
)] [=
initialization-expr
]
where:
name
is the name of a variable or function
array-spec
is a comma-separated list of dimension bounds
initialization-expr
is a complex constant expression. If
initialization-expr
is present,
entity-list
must be preceded by the double colon.
Description
The DOUBLE COMPLEX statement is an HP Fortran extension that declares the properties of
complex data that has greater precision than data of default type complex. The two parts of a
double complex value are each a double precision value.
