SELECTED_INT_KIND(3f)

DESCRIPTION
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.

STANDARD
Fortran 95 and later

CLASS
Transformational function

SYNTAX
RESULT = SELECTED_INT_KIND(R)

ARGUMENTS

R Shall be a scalar and of type INTEGER.

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
