Also I tried free42 on iOS and it also gets 0.0023 (wrong).
Ill update the initial post with the new values.

There is nothing wrong here.

The tangent of pi/24 degrees is 0,00228463462331349894308299181233...
The tangent of pi/24 radians is 0,131652497587395853471526457409...


So just set the correct angular mode and you'll get a correct result.
With all of the mentioned calculators. There's nothing wrong with them at all.

OK, I understand about the precision, no issues.

As of now, the problem remains that Torsten Manz HP15c calculator gives the RAD result even in DEG mode. Can someone else confirm this behavior so we can send a bug report to Torsten?
That is why I got confused and started trying different calculators in DEG mode.
Google displays the result in RAD (without explicit mentioning about RAD/DEG)
