.. index:: maximum value

.. function:: MAX

  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.

  :samp:`{Standard}:`
    Fortran 77 and later

  :samp:`{Class}:`
    Elemental function

  :samp:`{Syntax}:`
