Method Detail

evaluate

public final 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.
