Inquiry Intrinsic Functions

The following table lists inquiry intrinsic functions. Unless noted, inquiry intrinsic functions can be used in specification expressions.

Name	Description
ALLOCATED	Determines whether an allocatable variable is allocated.
ASSOCIATED	Determines if a pointer is associated or if two pointers are associated with the same target.
BIT_SIZE	Returns the number of bits in an integer type.
CACHESIZE	Returns the size of a level of the memory cache.
COSHAPE	Returns the sizes of codimensions of a coarray.
COMMAND_ARGUMENT_COUNT ^¹	Returns the number of command-line arguments.
DIGITS	Returns number of significant digits for data of the same type as the argument.
EOF	Determines whether a file is at or beyond the end-of-file record.
EPSILON	Returns the smallest positive number that when added to one produces a number greater than one for data of the same type as the argument.
EXTENDS_TYPE_OF	Determines if a derived type extends another derived type.
GET_TEAM ^¹	Returns a variable of type TEAM_TYPE that describes a team of images that for the team inquired about. TEAM_TYPE is defined in the intrinsic module ISO_FORTRAN_ENV.
HUGE	Returns the largest number that can be represented by numbers of the type of the argument.
IARGC	Returns the index of the last command-line argument.
INT_PTR_KIND	Returns the INTEGER KIND that will hold an address.
IS_CONTIGUOUS	Returns whether an array is contiguous.
KIND	Returns the value of the kind parameter of the argument.
LBOUND	Returns the lower bounds for all dimensions of an array, or the lower bound for a specified dimension.
LCOBOUND	Returns the lower cobounds for all codimensions of a coarray, or the lower cobound for a specified codimension.
LEN	Returns the length of a character expression.
LOC ^¹	Returns the address of the argument.
MAXEXPONENT	Returns the largest positive decimal exponent for data of the same type as the argument.
MINEXPONENT	Returns the largest negative decimal exponent for data of the same type as the argument.
NARGS	Returns the total number of command-line arguments, including the command.
NEW_LINE	Returns a newline character.
PRECISION	Returns the number of significant digits for data of the same type as the argument.
PRESENT	Determines whether an optional argument is present.
RADIX	Returns the base for data of the same type as the argument.
RANGE	Returns the decimal exponent range for data of the same type as the argument.
RANK	Returns the rank of a data object.
SAME_TYPE_AS	Determines if two polymorphic objects have the same dynamic type.
SELECTED_INT_KIND	Returns the value of the kind parameter of integers in range `r`.
SELECTED_REAL_KIND	Returns the value of the kind parameter of reals with (optional) first argument digits and (optional) second argument exponent range. At least one optional argument is required.
SHAPE	Returns the shape of an array or scalar argument.
SIZE	Returns the size of an array or the size of one extent of the array.
SIZEOF	Returns the number of bytes of storage used by the argument.
STORAGE_SIZE	Returns the number of bits occupied by an object.
TINY	Returns the smallest positive number that can be represented by numbers of type the argument.
UBOUND	Returns the upper bounds for all dimensions of an array, or the upper bound for a specified dimension.
UCOBOUND	Returns the upper cobounds for all codimensions of a coarray, or the upper cobound for a specified codimension.
¹ This function cannot be used in a specification expression because it is not a Fortran standard inquiry function.
