public class CubeFunctionInfo : FarPoint.CalcEngine.FunctionInfo
    {
      public override string Name { get { return "CUBE"; } }
      public override int MinArgs { get { return 1; } }

      public override object Evaluate (object[] args)
      {
        double num = FarPoint.CalcEngine.CalcConvert.ToDouble(args[0]);
        return num * num * num;
