    Hello, Using Delphi 10.4.2 I get different rounded values using below code. Purpose is to round up and have 13.98 for both. uses System.Math; procedure TForm1.Button1Click(Sender: TObject); var ToBeRounded: Double; Rounded: Double; begin ToBeRounded := 55.9 * 0.25; Rounded := SimpleRoundTo(ToBeRounded, -2); ShowMessage(ToBeRounded.ToString() + ' ' + Rounded.ToString()); // ToBeRounded is 13.975 and Rounded is 13.97 at this point Rounded := SimpleRoundTo(13.975, -2); ShowMessage(Rounded.ToString); // Rounded is 13.98 at this point end; If one reads help file it has following table for expected results I do not have deep floating point knowledge. I basically know they have a lot more digits than displayed. My question is, how can I always get 13.98 as result using multiplications and such. Thanks & Regards, Ertan
