| Description: | Returns the total number of elements in an array, or the extent of an array along a specified dimension. | ||
| Class: | Inquiry function; Generic | ||
| Arguments: | ARRAY | Must be an array (of any data type). It must not be a disassociated pointer or an allocatable array that is not allocated. It can be an assumed-size array if DIM is present with a value less than the rank of ARRAY. | |
| DIM (opt) | Must be a scalar integer with a value in the range 1 to n, where n is the rank of ARRAY. | ||
| KIND (opt) | Must be a scalar integer initialization expression. | ||
| Results: | The result
is a scalar of type integer. If KIND is present, the
kind parameter of the result is that specified by KIND; otherwise, the kind
parameter of the result is that of default integer. If the processor
cannot represent the result value in the kind of the result, the result
is undefined.
If DIM is present, the result is the extent of dimension DIM in ARRAY; otherwise, the result is the total number of elements in ARRAY. The setting of compiler options that specify integer size can affect the result of this function. | ||
Examples
If B is declared as B(2:4, -3:1), then SIZE (B, DIM=2) has the value 5 and SIZE (B) has the value 15.
