Throws:: EvaluationException

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. eval protected abstract double eval(ValueEval[] args, int srcCellRow, int srcCellCol) throws EvaluationException Throws: EvaluationException
