Same here. I repeatedly closed the Welcome screen and opened it again with no luck. After I restarted the IDE it showed up though. A bug ???

For native linux ARM support, there is freepascal. See https://wiki.freepascal.org/Lazarus_on_Raspberry_Pi

@dummzeuch and @Rollo62 No matter if you use '123.4' or '123,4'. It gives error in position 4 with a result of 123. Oops, my bad. Indeed when a float is passed, '123.4' results in 123.4 with error = 0, while '123,4' results in 123 with error = 4. There must be an error in the docs: Though one sentence later it says: Which implies that a real type must not be a whole number.

Look into Axolot XLSSpreadsheet. Their spreadsheet components have been around a very long time. https://www.axolot.com/xss.htm

Why would you need an excuse to do that. Go for it anyway!

A faster version of Pos() is finally in place. Thanks @Stefan Glienke for making it happen.

I still find the fastcoders purepascal Pos() faster for 64 bit in this modification: https://stackoverflow.com/a/20947429/576719

Borland filed a lawsuite against Microsoft at the time of Hejlsberg's departure though. See https://www.wsj.com/articles/SB863034062733665000 >Borland Charges Microsoft Stole Away Its Employees

They profile gender, race, age, social and physical variations, education, income. Next step is political preference, sexual preference, previouse convictions, racism.

Ok, yes a warning would be expected!

I don't know what you mean. For sure it gives a range check error.

@Mike Torrettinni If you are looking for a faster Pos() function in 64-bit mode, see https://stackoverflow.com/a/20947429/576719 It is based on Fastcoders purepascal version. Just added some details to make it compile in 64-bit.

Well. there is no secret that LU RD is short for Leif Uneus R&D Manager of Opsis AB, a company that provides analysers and software for industrial and environmental analysis of gases and particulates. A company started 36 years ago by me and my business partner. Core software in the analysers is built with Turbo Pascal 7. Delphi is a tool for our software for data management, analysis and reporting.

See the question from David at SO, years ago: https://stackoverflow.com/q/9422703/576719

As I understand it, the source code of Mitovs libraries can be purchased. I would never rely of a library without the source.

Is it not enough to declare DefaultCW8087 et al. as threadvar?

Like using the $STRONGLINKTYPES directive? http://docwiki.embarcadero.com/RADStudio/en/Strong_link_types_(Delphi)

If a class is not used, RTTI information is stripped off by the compiler, See https://stackoverflow.com/q/10613094/576719

Whether a typed constant is immutable or not is controlled by a compiler switch. See http://docwiki.embarcadero.com/RADStudio/en/Writeable_typed_constants_(Delphi)

The type is still extended, but the value will be as a single(0.1) program Project169; {$APPTYPE CONSOLE} uses System.SysUtils, System.TypInfo; type TTypeInfo = class class function ShowTypeInfo<T>(const X: T) : String; end; class function TTypeInfo.ShowTypeInfo<T>(const X: T) : String; var LTypeInfo: PTypeInfo; begin LTypeInfo := TypeInfo(T); Result := LTypeInfo.Name; end; const F1 : Single = 0.1; F2 = Single(0.1); // <- Extended type, with the value of a single 0.1 F3 = Extended(0.1); begin WriteLn(TTypeInfo.ShowTypeInfo(F1):10,':',F1); WriteLn(TTypeInfo.ShowTypeInfo(F2):10,':',F2); WriteLn(TTypeInfo.ShowTypeInfo(F3):10,':',F3); ReadLn; end. Outputs: Single: 1.00000001490116E-0001 Extended: 1.00000001490116E-0001 Extended: 1.00000000000000E-0001

@Vandrovnik, Still both F1 and F2 are of type extended.

Use StopWatch := TStopWatch.Create to initialize a new TStopWatch value in a stopped condition or StopWatch := TStopWatch.StartNew to return a started stopwatch. See http://docwiki.embarcadero.com/Libraries/Rio/en/System.Diagnostics.TStopwatch.Create

Sorry @DavidHeffernan, but in the file posted by @pyscript his proposed function InterlockedCompareExchange128 returns a boolean.
