Intel Fortran Language Reference
default logical
The kind for logical constants if no kind type parameter is specified. The default logical kind is
affected by compiler options that specify integer size. If no compiler option is specified, default
logical is LOGICAL(4) (LOGICAL*4). See also default integer.
default real
The kind for real constants if no kind type parameter is specified. The default real kind is
determined by the compiler option specifying real size. If no compiler option is specified, default
real is REAL(4) (REAL*4).
If a real constant is encountered that is outside the range for the default, an error occurs.
deferred-shape array
An array pointer (an array with the POINTER attribute) or an allocatable array (an array with the
ALLOCATABLE attribute). The size in each dimension is determined by pointer assignment or
when the array is allocated.
The array specification contains a colon (:) for each dimension of the array. No bounds are
specified.
definable
A property of variables. A variable is definable if its value can be changed by the appearance of its
name or designator on the left of an assignment statement. An example of a variable that is not
definable is an allocatable array that has not been allocated.
defined
For a data object, the property of having or being given a valid value.
defined assignment
An assignment statement that is not intrinsic, but is defined by a subroutine and an
ASSIGNMENT(=) interface block. See also derived type and interface block.
defined operation
An operation that is not intrinsic, but is defined by a function subprogram containing a generic
interface block with the specifier OPERATOR. See also derived type and interface block.
denormalized number
A computational floating-point result smaller than the lowest value in the normal range of a data
type (the smallest representable normalized number). You cannot write a constant for a
denormalized number.
