                          ValueEval arg2)
Description copied from interface: Function3Arg
see Function.evaluate(ValueEval[], int, int)

Specified by:
evaluate in interface Function3Arg

evaluate

                          ValueEval arg3)
Description copied from interface: Function4Arg

Specified by:

evaluate

public ValueEval evaluate(int srcRowIndex,
                          int srcColumnIndex,
                          ValueEval arg0,

                          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.
