      public override int MinArgs { get { return 1; } }
      public override int MaxArgs { get { return 1; } }
      public override object Evaluate (object[] args)
      {
        double num = FarPoint.CalcEngine.CalcConvert.ToDouble(args[0]);
        return num * num * num;
      }
    }

DialogResult dlg;

cfs = (FarPoint.Win.Spread.Model.ICustomFunctionSupport)fpSpread1.ActiveSheet.Models.Data;
cfs.AddCustomFunction(new CubeFunctionInfo());
fpSpread1.ActiveSheet.SetFormula(1, 1, "CUBE(4)");
