     *           Adds the given value to the field's current value.

     *           If the field is not an integer or double, or if the field does not yet

     *           If either of the given value or the current field value are doubles,
     *           both values will be interpreted as doubles. Double arithmetic and

     *           If there is positive/negative integer overflow, the field is resolved
     *           to the largest magnitude positive/negative integer.
     *     @type \Google\Cloud\Firestore\V1beta1\Value $maximum
     *           Sets the field to the maximum of its current value and the given value.

     *           If the field is not an integer or double, or if the field does not yet

     *           0, 0.0, and -0.0 are all zero. The maximum of a zero stored value and

     *           the current field value.
     *           If the field is not an array, or if the field does not yet exist, it is
     *           first set to the empty array.
     *           Equivalent numbers of different types (e.g. 3L and 3.0) are
