Hello,

When I try to build the app I got the following issue:

Android resource compilation failed
/PalmCalc-master/app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:543: error: inner element must either be a resource reference or empty.
/PalmCalc-master/app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:681: error: unescaped apostrophe in string
"Android's programming language itself is switching from Java to Kotlin".
/PalmCalc-master/app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml:650: error: not a valid string.
/PalmCalc-master/app/build/intermediates/incremental/mergeDebugResources/merged.dir/values/values.xml: error: file failed to compile.
Can you please support me in order to build it with android studio 3.5.3

Thanks,
Chaker

Please insert info about de programmer and this web page. Thanks.

Please add some screenshots showing the main application window and settings screens to your application page in the F-Droid directory.

Press FSE to get SCI mode, then TAB to get 4 significant digits. Type .45/2.2 to get 2.045E-1. Press STO (which requires ALT). You currently get an error because of bug #17. Press AC. There is now no ALT on the display. However, pressing 2 you get E.

It would be great if you could add a function for the y root of x. It could go right above the x to the power of y key using the shift key.

A button that swaps the to and from units in the Unit Converter

Unnecessary.

Pls include an option to add custom units for conversion

After startup a message is displayed that the display size is not supported. But afterwards the app looks fine.

Phone: Motorola One Vision
Display: 2520 x 1080

I suggest adding an option to disable the result animation when you press =

I guess the animation is fine, but some would like to get an instant result, just as you would get with a physical calculator, hence this request.

Press FSE and move to SCI mode. Use TAB to get 4 decimal digits. Press .45/2.2, to get 2.045E-1 and try to use STO. You get an error (Save failed).

I see the last commit was made almost two years ago, so it seems this project is dead. Is this true (which would be a pitty)?

in a normal scientific calculator pressing
1 / 2 E - 3
one gets an expression interpreted as
1/(2*10^(-3))
that is 500

In PalmCalc 2019, the best approximation of E is Exp, but pressing
1 / 2 E - 3 )
one obviously gets and expression interpreted as
1/2*10^(-3) that is 0.0005

This may appear a bit confusing to those using regular calculators where both Exp and an "E" to help entering numbers in scientific notation are provided. More so, becase "Exp" is not in the upper zone of the keyboard, but where "E" is generally found in regular scientific pocket calculators. Please, consider adding "E" to help quickly enter numbers in scientific notation and leaving out Exp, since one has already 10^x.

In the settings you can set the start screen. This is the screen which is opened at startup after the application was fully unloaded from memory. The setting does include the currency converter which does not exist any more. This causes all screens which follow, to point to the wrong startup screen.

For example, if you select the currency converter as start screen, the basic calculator will start. If you select the BMI calculator as start screen, the about box will start.

(tested version 3.0.4)

org.javia.arity 'Arity' is an arithmetic engine for for Java, by Mihai Preda.

It's currently used in:

com.cybrosys.basic.HistoryAdapter
com.cybrosys.basic.Logic
com.cybrosys.scientific.EventListener
com.cybrosys.scientific.HistoryAdapter
com.cybrosys.scientific.Logic
com.cybrosys.unit.Calculate

(Some of these classes may be duplicates, but that's a problem for another issue)

Originally a Freshmeat project, the project was apparently moved to Google Code some time after 2008. There are no working links for this URL; apparently it was excluded from the Google Code archive.

The code was imported from google code several times, by several different people. The most notable imports are:

• By the original author in 2014. The project was renamed to Arithmetic, then seemingly reabandoned. Uses an obscure python build system setup.py.
• By Hoijui in 2016. This version includes a standard Maven pom.xml, and successfully builds as of this writing.
• A fork from Preda's version by piusvelte, which includes original work to fix precision errors by using Java's BigDecimal API
• A fork from Hoijui's version apparently fixes mathematical errors; but the comments & commit messages are in Chinese, so these were overlooked originally.

For now, using the embedded JAR does work. But this project needs a better solution going forward. Checking binaries into git is never a good strategy, and relying on abandoned code that can't be updated is also a very bad idea.

Proposed Solution

A Jitpack build of Hoijui's version currently succeeds; in order to guarantee code availability going forward, this version should be forked into a repo controlled by this project.

From there, we can also include the improvements done by piusvelte

In the fdroid version not found the del button, so don't can delete number without delete with ac button

Add functionality to the scientific calculator, to be able to switch &perform conversions between different numerical bases (radixes): decimal, hexadecimal, octal, binary

Watts, HP, BHP, Joules, etc

In the BMI calculator in metric mode changing the weight doesn't affect the result.
