MAX --- Maximum value of an argument list
*****************************************

.. function:: MAX(A1, A2 , A3 , ...)

  Returns the argument with the largest (most positive) value.

  :param A1:
    The type shall be ``INTEGER`` or
    ``REAL``.

  :param A2}, {A3}, ...:
    An expression of the same type and kind
    as :samp:`{A1}`.  (As a GNU extension, arguments of different kinds are
    permitted.)

  :return:
    The return value corresponds to the maximum value among the arguments,
    and has the same type and kind as the first argument.

  Standard:
    Fortran 77 and later

  Class:
    Elemental function

  Syntax:
    .. code-block:: fortran

      RESULT = MAX(A1, A2 [, A3 [, ...]])
