It's probably possible to calculate this on the dm42 you'd just have to write an arbitrary precision program, then calculate it.

Assuming the problem is related to precision.

Thanks ya, just making a program for work.

I would like to make a program that solves matrices. Part of this program requires me to manipulate a matrix's I and J indices by recalling and storing them as well as incrementing them such as I+ and J+. I know these functions are possible because they are in the manual I just can not seem to find ...

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)...

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 ...

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...

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...

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 ...

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.

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...
