43S Alternative key layout --> WP43C

[Jaymos]

Thanks for this project!

To build, I like to use Clang, rather than GCC because of some nice tooling that it provides for profiling and debugging. However, C43 uses a gcc-only extension (which WP43S doesn't use): nested functions in C (i.e. void blah() { void meh() {} }). Would you consider a patch to extract those from their outer function?

It'd make C43 more portable (and respectful of the C standard!).

We discontinued the use of the nested functions, and we also updated the header files with proper external declarations so that there are no such errors. (To be honest I used that in ignorance of the standard!)

The latest revisions (see the ‘latest’ branch) compile on my Windows gcc and Mac clang compilers with only minor warnings.

Thanx for the comment.

There seems to be a bug with the display format in the WP43C simulator.
At first I thought the problem was with the constants library, but then I saw that it affects any very big or very small number.
For example Avogadro's number, with SCI₃ or ENG₃, it displays correctly.

With FIX₃ or SIG₃ , the display is zero.

The WP43S does not have this problem.

I will fix it, thanx for finding it!

Found the FIX bug, which was also evident in the SIG mode.
Fixed it in the development branch. Will upload a sim in a few days.
Thanx

This is great.
Pocket calculators came out in the 1970s. Why, I wonder, has it taken until now for (one) calculator to appear that displays significant figures when this is what is needed for most everyday and engineering tasks?

I loved it from the moment I first saw the hack on the WP34S from Nigel(UK). And some changes by Bit, here.

Googling it now to find the Bit and Nigel references to quote, I found my own document, which I have forgotten I had written, with an example showing sigfig, here.

Did not know there was still interest. I got complaints that the doc that I shared does not have working links. It seems those were stripped by who-ever (or which-ever machine) placed it on that doc website. I have no knowledge of that.

It is a bit off-topic here, so to close the loop and WP34S discussion, just a reference to the original document (with working PDF links) inside my last 100 MB firmware/doc bundle that I published here in 2019.
