SYNOPSIS

impure elemental function anyscalar_to_int64(valin) result(value)
    class(*),intent(in) :: valin
    integer(kind=int64) :: value

DESCRIPTION

This function uses polymorphism to allow arguments of different types as input. It is typically used to create other procedures that can take many scalar arguments as input options, equivalent to passing the parameter VALUE as int(VALUE,0_int64) for integer; nint(VALUE,0_int64) for real values, returning 0_int64 for .true. and 1_int64 for logical, and the same as int(VALUE,0_int64) for character variables if the character variables represent an integer value.

OPTIONS

VALUEIN
input argument of a procedure to convert to type INTEGER(KIND=int64).

RESULTS

The value of VALUIN converted to INTEGER(KIND=INT64).

EXAMPLES

Sample program

    program demo_anyscalar_to_int64
    use, intrinsic :: iso_fortran_env, only : int8, int16, int32, int64
    implicit none
       ! call same function with many scalar input types
       write(*,*)squarei(huge(0_int8)),huge(0_int8) , &
       & ’16129’
       write(*,*)squarei(huge(0_int16)),huge(0_int16) , &
       & ’1073676289’
       write(*,*)squarei(huge(0_int32)),huge(0_int32) , &
       & ’4611686014132420609’
       write(*,*)squarei(huge(0_int64)),huge(0_int64) , &
       & ’85070591730234615847396907784232501249’
    contains
    !
    function squarei(invalue)
    use M_anything, only : anyscalar_to_int64
    class(*),intent(in)  :: invalue
    doubleprecision      :: invalue_local
    doubleprecision      :: squarei
       invalue_local=anyscalar_to_int64(invalue)
       squarei=invalue_local*invalue_local
    end function squarei
    !
    end program demo_anyscalar_to_int64
