Method Detail

### evaluate

    public ValueEval evaluate(int srcRowIndex,
                              int srcColumnIndex,
                              ValueEval arg0,
                              ValueEval arg1,
                              ValueEval arg2)

  Description copied from interface: `Function3Arg`
  see `Function.evaluate(ValueEval[], int, int)`

  Specified by:
    `evaluate` in interface `Function3Arg`

### evaluate

    public ValueEval evaluate(int srcRowIndex,
                              int srcColumnIndex,
                              ValueEval arg0,
                              ValueEval arg1,
                              ValueEval arg2,
                              ValueEval arg3)

  Description copied from interface: `Function4Arg`
  see `Function.evaluate(ValueEval[], int, int)`

  Specified by:
    `evaluate` in interface `Function4Arg`

### evaluate

    public ValueEval evaluate(int srcRowIndex,
                              int srcColumnIndex,
                              ValueEval arg0,
                              ValueEval arg1,
                              ValueEval arg2,
                              ValueEval arg3,
                              ValueEval arg4)

### evaluate

    public ValueEval evaluate(ValueEval[] args,
                              int srcRowIndex,
                              int srcColumnIndex)

  Specified by:
    `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`.

### evaluate

    protected double evaluate(double[] ds)
                       throws EvaluationException

  Throws:
    `EvaluationException`

### evaluate

    protected abstract double evaluate(double rate,
                                       double arg1,
                                       double arg2,
                                       double arg3,
                                       boolean type)
                                throws EvaluationException

  Throws:
    `EvaluationException`
