SELECTED_INT_KIND — Choose integer kind#
-
SELECTED_INT_KIND(R)#
SELECTED_INT_KIND(R)
return the kind value of the smallest integer type that can represent all values ranging from -10^R (exclusive) to 10^R (exclusive). If there is no integer kind that accommodates this range,SELECTED_INT_KIND
returns -1.- Parameters
R – Shall be a scalar and of type
INTEGER
.
- Standard:
Fortran 90 and later
- Class:
Transformational function
- Syntax:
RESULT = SELECTED_INT_KIND(R)
- Example:
program large_integers integer,parameter :: k5 = selected_int_kind(5) integer,parameter :: k15 = selected_int_kind(15) integer(kind=k5) :: i5 integer(kind=k15) :: i15 print *, huge(i5), huge(i15) ! The following inequalities are always true print *, huge(i5) >= 10_k5**5-1 print *, huge(i15) >= 10_k15**15-1 end program large_integers
