REAL
Declares entities of type real.
Syntax
REAL [ kind-spec ] [[, attrib-list ] ::] entity-list
kind-spec is the kind type parameter that specifies the range and precision of the
entities in entity-list . kind-spec takes the form:
([KIND=] kind-param )
where kind-param can be a named constant or a constant expression that
has the integer value of 4, 8, or 16. The size of the default type is 4.
As an extension, kind-spec can take the form:
* len-param
where len-param is the integer 4, 8, or 16 (default = 4).
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, and initialization-expr is a
real constant expression. If initialization-expr is present, entity-list
must be preceded by the double colon.
