Method Details

checkValue

public static void checkValue(double result)
                       throws EvaluationException

Throws:

EvaluationException - (#NUM!) if result is NaN or Infinity

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.
