    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.
