As soon as this hardware (keyboard/display option) is announced - I'm pre-ordering. Nice work.

I guess the 43S doesn't have the ability show SI prefixes or enter SI prefixes?

For example .00001 in ENG mode shows as 10X10-6
but have it show as 10µ instead.

At least I couldn't find anything in the manual for the 43S or DM41X or DM42.

You're right, none of these three calcs has this feature. Why not? I can only speak for the WP43S but:
  • the more or less 'common' SI prefixes cover 30 orders of magnitude using 13 prefixes (max. 36 using 15).
  • we cover a real number range of some 12000 orders of magnitude.
  • is the effort for a special display mode worthwile for such a small section of the number range? While people using these prefixes have to learn them anyway? An output of 123p is useless if you don't know that this p stands for 10^(-12).
So far, I'm not convinced that SI prefixes in calculator output are the stuff.

I can see why SI prefixes would be nice to have, but since most people probably only know from pico to tera, having to learn those that exceed this range would kind of defeat the purpose of making things easier, I guess. Not to mention the inconsistent user experience when some numbers get SI prefixes and others do not.

Thank you for confirming I was not overlooking the feature.

I can only say for myself who does some electronics work I find it very handy and helps prevent entry errors.

TBH - know your number system? These calcs work on numbers, not on intuition. You should rationalize your results - that is, if you know what it is you are asking.

The vanilla version does not. I wanted it though for my frequent excursions in electr(on)ic use, and I actually use the range from p to M. So I made it display the usual culprits between f and T, and have multiplier buttons too. I had no want or need to implement more than that; if it exceeds the text range, it changes over to the normal ENG notation. These were some of the first changes I made to the 43S UI about 2 years ago, and I still like it and occasionally use the UNIT display mode.

It therefore can be done, see my image below. As Walter's has said on more than one occasion, on this forum and others, (my paraphrasing of course) is that if you want it bad enough on your 43S, argue louder and convince Walter. I do have to warn that sometimes it is easier to make it yourself and stop arguing.

Very interesting. Did you do this by modifying the source code or program it as a type of function with the calculator (I do not at present own any SwissMicro calculators)?

For sake of clarity, loudness alone doesn't win. Convincing's better. And it helps considerably if you're not the only person wanting a certain feature. With respect to SI prefixes, I don't get the impression it's a wish of a majority.

I completely understand it's not wanted by very many and isn't going to be implemented.

I'm only interested now in how hard-to-do and functional it would be when added by a user.
