    I've been diving deep into Embarcadero's Androidapi.JNI units, especially Androidapi.JNIBridge, and I'm truly amazed by the software design. The implementation of TJavaGenericImport showcases an incredibly high level of abstraction and modularity, making it both elegant and powerful. The way these units bridge Delphi with Java is nothing short of genius. I can't help but wonder who the developer (or team) was behind this architectural masterpiece. Does anyone know who contributed to these units? Or perhaps some background on the development process for this part of the RTL? I'm keen to learn more about the design philosophy and the thought process that led to such an outstanding implementation.

    program Project2; {$APPTYPE CONSOLE} {$R *.res} uses System.SysUtils, System.Math; begin var a,b:double; a:=1.015; b:=2.275; writeln(round(a*Power(10,2))); writeln(round(b*Power(10,2))); readln; end. Please run as 32 and 64bit I split this off to its own topic, so that future readers will find this tightly packaged. Please consider creating a new thread for any question/issue/remark that is not exactly the same as the opening post of a thread - Sherlock

    Hello, I need to fire some action very precisely AFAIK I cannot fully trust to Ttimer(accuracy) Maybe question is stupid or trivial but how get something similar like below but using the most precise method(TStopwatch) procedure TForm1.Timer1Timer(Sender: TObject); begin // Do something every 1 second(timer interval set to 1000ms) end;

    Hi all, what is the fastest way to compare two vars of the TIntegerDynArray type? Thank you in advance for your suggestions.

    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
