    Iterative Calculation
    In This Topic

    Iterative calculation is performed to repeatedly calculate a function until a specific numeric condition is met. GcExcel allows you to enable and perform iterative calculations by using EnableIterativeCalculation property of IFormulaOptions interface. Additionally, you can also set or retrieve the following:

    For example, if MaximumIterations is set to 10 and MaximumChange is set to 0.001, GcExcel will stop calculating either after 10 calculations, or when there is a difference of less than 0.001 between the results.


    Refer to the following example code to perform iterative calculation in a worksheet by performing 10 iterations.

    Copy Code
    //create a new workbook
    Workbook workbook = new Workbook();
    //enable iterative calculation
    workbook.Options.Formulas.EnableIterativeCalculation = true;
    workbook.Options.Formulas.MaximumIterations = 10;
    var worksheet = workbook.Worksheets[0];
    worksheet.Range["A1"].Formula = "=B1 + 1";
    worksheet.Range["B1"].Formula = "=A1 + 1";
    Console.WriteLine("A1:" + worksheet.Range["A1"].Value.ToString());
    Console.WriteLine("B1:" + worksheet.Range["B1"].Value.ToString());
