pure elemental function anyscalar_to_double(valuein) result(d_out)
class(*),intent(in) :: valuein doubleprecision :: d_out
This function uses polymorphism to allow input arguments of different types. It is used to create other procedures that can take many scalar arguments as input options.
VALUEIN input argument of a procedure to convert to type DOUBLEPRECISION. May be of KIND kind=int8, kind=int16, kind=int32, kind=int64, kind=real32, kind=real64, or kind=real128
D_OUT The value of VALUIN converted to doubleprecision (assuming it is actually in the range of type DOUBLEPRECISION).
