    • evaluateArray

      ValueEval evaluateArray(ValueEval[] args, int srcRowIndex, int srcColumnIndex)
      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.
