    • evaluate

      public ValueEval evaluate(ValueEval[] args, int srcCellRow, int srcCellCol)
      Specified by:
      evaluate in interface Function
      Parameters:
      args - the evaluated function arguments. Empty values are represented with BlankEval or MissingArgEval, never null.
      srcCellRow - row index of the cell containing the formula under evaluation
      srcCellCol - 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.
