public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval arg0)
```
    Description copied from interface: Function1Arg
    
    see Function.evaluate(ValueEval[], int, int)
    
    Specified by:
    
    evaluate in interface Function1Arg
  - evaluateArray
```
public ValueEval evaluateArray(ValueEval[] args,
                               int srcRowIndex,
                               int srcColumnIndex)
```
    Specified by:
    
    evaluateArray in interface ArrayFunction
    
    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.
