Precision of the Exponential Integral on DM42

I have programmed the exponential integral a couple of times and I have a problem with precision when x<-30 (on the DM42). This series is very similar to something like a Taylor series. At x = -30 and lower the algorithm has a serious problem with precision (only a couple of sig figs or none at all)...

Re: Feature requests

I installed free42 on my Arch Linux installation just to see this option. You're right! I think this should be changed to auto-repeat OFF/ON on the dm42 as you have it in your free42 simulator. I can't honestly tell a difference right now between slow/fast on the calculator (if I could, it may just ...

Re: Feature requests

Even though I complain about the WP34s I do not regret buying it and I do not plan to sell it. I do have some very important and regularly used functions programmed into ABCD and are those functions are rather complex and require high precision. The WP34s is excellent for this type of thing. Overall...

Re: Feature requests

Also, I know why people complain about the keypad on the DM42. It's because sometimes you long-push a number and it double or triple pushes it. To me, it doesn't make sense that the buttons are auto-push when you hold them down. If you just removed the auto-button (or at least had an option to remov...

Re: Feature requests

I own a wp-34s. I do like it and that it has greek letters. Just a couple of things I don't like: 1. Small memory 2. can't enter long numbers into programs 3. Lackluster solver 4. Stickers on buttons make me too careful, though the buttons do feel better than DM42. WP-34s may have greek letters but ...

Re: Feature requests

Add the greek alphabit as an additional option. When you are in alpha mode, make some type of key combination put the greek letters (alpha beta etc) on the soft menu.

Almost every equation I use has one of those characters.

Re: Looking forward to the DM42 update utilizing the Free42 2.023 update...

An up to dat DM42 is a better DM42 :) I disagree. The changes in 2.023 are small, highly specialized and very unlikely to matter to almost anyone, and simply do not warrant a new release of DM42 on their own. It makes more sense to spend the limited time David has to continue work on other forthcom...

DM43 triple coin battery design?

Why not have the DM43 be a triple coin battery design? I've heard stories of other calculators with such a design that had a battery life expectancy on the order of decades. My DM42 still shows "full" and I've been using it almost daily for a couple of months, but still...

Re: We need you for the 43S. Yes, you!

I'm not really against it. I have never tried it on that side. If the majority want it then maybe there is some advantage to it I can't think of. I am more curious than anything as to why most people prefer it that way.

Personally, I'd say I am fairly agnostic.
