        evaluate in interface Function
        Parameters:
        args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
        srcRowIndex - row index of the cell containing the formula under evaluation
        srcColumnIndex - column index of the cell containing the formula under evaluation
        Returns:
        The evaluated result, possibly an ErrorEval, never null. Note - Excel uses the error code #NUM! instead of IEEE NaN, so when numeric functions evaluate to Double.NaN be sure to translate the result to ErrorEval.NUM_ERROR.
