Language Reference c r is a constant or the symbolic name of a constant is an unsigned positive integer constant or the symbolic name of a constant. This form of the DOUBLE COMPLEX statement is also an extension to the FORTRAN 77 language. The rules for data initialization are the same as for the DATA statement. Example: DOUBLE COMPLEX A/(4D4,5.1D4)/, B(10)/10*(5D1,3.1D1)/ In the previous example, A is initialized with the double precision complex constant (4D4,5.1D4) and each element of the array B is initialized with the double precision complex constant (5D1,3.1D1). 50 DOUBLE COMPLEX Statement
FORTRAN Statements 2.22 DOUBLE PRECISION Statement The DOUBLE PRECISION statement is a type declaration statement and can be used to declare a name to be of type double precision. The implicit type of the name, whether defined by the "first letter rule" (see the chapter entitled "Names, Data Types and Constants" on page 151) or by an IMPLICIT statement, is either confirmed or overridden. However, once a name has been declared to be of type double precision, it cannot appear in another type declaration statement. There are various forms of the DOUBLE PRECISION statement. The following sections describe them. 2.22.1 Standard DOUBLE PRECISION Statement DOUBLE PRECISION name [,name] ... where: name is a variable name, array name, array declarator, symbolic name of a constant, function name or dummy procedure name. This form is the standard form of the DOUBLE PRECISION statement. Example: DIMENSION C(-5:5) DOUBLE PRECISION A, B(10), C In the previous example, A is defined to be a variable of type double precision and B and C are defined to be arrays of type double precision. 2.22.2 Extended DOUBLE PRECISION Statement: Data Initialization DOUBLE PRECISION name [/cl/] [,name[/cl/]] ... where: name cl is as described in the previous section. is a list of the form: k [,k] ... k is one of the forms: c r*c (equivalent to r successive appearances of c) DOUBLE PRECISION Statement 51
