インテル® Fortran コンパイラー 19.0 デベロッパー・ガイドおよびリファレンス

The following table lists inquiry intrinsic functions.

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.
COMMAND_ARGUMENT_COUNT	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.
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.
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.
LEN	Returns the length of a character expression.
LOC	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.
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.
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.
SIZEOF	Returns the number of bytes of storage used by the argument.
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.
