Perfekt, Besseres habe ich nicht gefunden!

Natürlich geht dieser Rechner weit über meine Fähigkeiten hinaus. Wichtig für mich ist aber:
Anzeige der Rechenschritte zur nachträglichen Kontrolle, schnelles Hin- und Herwechseln zur Bedienungsanleitung, völlig werbungsfrei!

Für mich die beste Taschenrechner-App

Aktualisierung meiner früheren Bewertungen:
Nach rund einem Dutzend Versuchen mit anderen Taschenrechner-Apps bin ich vor mittlerweile zehn Jahren auf diese gestoßen. Ich kenne schon die Vorgänger für Palm OS, die ich seinerzeit viel genutzt habe.
Der wissenschaftliche Rechner kopiert den bewährten Aufbau klassischer Taschenrechner der 80er Jahre. Alternativ gibt es D.A.L.-, Einheiten- und Logik-Rechner, sowie ein integriertes Handbuch und eine Watch-App. Außerdem wird die App kontinuierlich gepflegt.
Ich benutze tatsächlich keine andere Rechner-App mehr.

Ganz gut

Das Komma hinter jeder Zahl nervt. Was soll das? Sonst gut.

Deg/Rad Mode Switching Bug - Incorrect Angle Unit Display

I'm experiencing an issue with the scientific calculator app where it's giving me the same result for the inverse tangent function (tan^-1(63/200)) regardless of whether it's set to radians (RAD) or degrees (DEG).

The app shows 0.315 in both RAD and DEG modes, whereas I would expect it to display the result in radians when in RAD mode and convert it to degrees when in DEG mode, which should be approximately 17.48 degrees.

It seems like there could be a bug with the mode switching or the unit display functionality.

Hopefully this gets fixed as hard to trust otherwise.

Nice to have history displayed an BEDMAS works correctly.
