Transformational Intrinsic Function (Generic): Returns the value of the kind parameter of an integer data type.
result = SELECTED_INT_KIND (r)
r |
(Input) Must be scalar and of type integer. |
The result is a scalar of type default integer. The result has a value equal to the value of the kind parameter of the integer data type that represents all values n in the range of values n with -10 r< n < 10 r.
If no such kind type parameter is available on the processor, the result is -1. If more than one kind type parameter meets the criteria, the value returned is the one with the smallest decimal exponent range. For more information, see Model for Integer Data.
SELECTED_INT_KIND (6) = 4
The following shows another example:
i = SELECTED_INT_KIND(8) ! returns 4
i = SELECTED_INT_KIND(3) ! returns 2
i = SELECTED_INT_KIND(10) ! returns 8
i = SELECTED_INT_KIND(20) ! returns -1 because 10**20
! is bigger than 2**63
