For 1.x and 2.x versions, the version number is shown in the bottom right corner of the display. You may need to squint a little to see it. If you were unable to see it, you can select "Email Your Feedback" from the action menu in the top right corner. The version number is mentioned in the text of the email.
Beginning with version 3.0, the version is mentioned at the top of the info menu; press the (i) button to see it. As before, the version number is also mentioned in the text of the email that generated if you select "Email your Feedback".
Yes. Support for an external keyboard was added in Version 1.3.
You are operating in radiants mode (RAD); the "2-pi" symbol is shown at the top of the display. To change to degrees mode, execute the DEG command; the "2-pi" symbol will disappear. Now "30 SIN" produces "0.5".
The log is limited to 512 entries, above which the oldest entries will be removed.
Beginning with version 2.1, you can clear the log manually. Swipe upwards in the log viewer to reveal a card with action buttons.
Using the selector on the left, you can limit your actions to:
To delete the entire log, select "All Entries" and press the trash can icon.
To email today's entries, select "Today", press the share button and select Mail in the action sheet that will appear.
Basically, it selects entries that were added "on a day before today". If you were using the app every day, that would be the same as "yesterday". If you were using RPN 28x Calc only on Sundays, then for you, "recent" would mean "last Sunday".
When upgrading from version 2.x to 3.0, it may happen that the app crashes during its lauch cycle. You may see the app launch image and then nothing more.
This is due to a bug in version 3.0 when trying to decode data written by version 2.x.
Prior to the release of a fix, you can avoid this scenario by deleting the App from your device (and also deleting all of its data), and re-installing it from the App Store. Note that this will delete any variables and all values that you have had on your stack.
Support for matrices was added in version 3.0.
In pre-3.0 version, arrays of arrays are not supported. You may see a side effect of this when you add an array to the statistics array with the '
Σ+' command. What happens then is that the array is unpacked and its elements are added to the statistics array (which is purely one-dimensional).
Update: This has been fixed version 1.1.
When the FIX number formatting mode is enabled, then very large numbers may be too large to fit the screen and they will appear scaled and truncated. The corresponding number is intact, it is merely displayed badly.
Simple, please contact me.
Since all calculator commands use English names or abbreviations, it is not meaningful to create different versions for other languages. There are therefore no plans to create non-English versions of this application. Sorry.
Within the app, you can select "Email Your Feedback" from the (i)nfo menu. If you like, you can save the message as a draft (tap Cancel, then Save Draft) and continue editing it from within your email program.
Feel free to write your message in English, German, or Swedish.
Alternatively, you can send an email to firstname.lastname@example.org (don't put this address in your address book as it is temporary), or use the online contact form.
