Benchmark test e^x^3

RAM and CPU are only elements you need to assemble on a PCB, whether you use them to the maximum is another story. Still already the task to design a PCB takes lots of efforts and testing.

Developing a sound math library takes a lot of effort. The 50g had the culmination of a math library that was developed over 20 years by several people concurrently. Porting the effort is not easy. The cas of the prime is a specific version of Giac/Xcas (n1). There may be scarcity of manpower or priority about the topic of large numbers.

On the dm42 they used the math engine free42 developed over tens of years by Thomas Okken (n2). It is not that sound math libraries/engines are developed overnight.

Then you should not forget the economical factor. People are paid in companies to generate profit (or at least not too big losses), they are not going to work on edge cases ( few people would actually care to compute a function with a result over e300).

For example you likely don't know that the prime list can handle only 10 000 elements, although there is plenty of ram available. Why? because likely the code to handle limited lists is more economical to maintain and the likelihood that people would exceed that limit is near zero.
Still one with a bit of work can create a library to handle lists of lists and easily exceed million of elements.

You can always contribute yourself for improvements with additional programs, and then you will also see how much effort it is needed. (but you will learn a lot!)
Or you can even sponsor HP directly with several hundred thousand dollars so they can fix what is important for you.

An observation: I see that youtubers with little knowledge of the calculators they use or math do more harm than good, also because they may be corrected but they don't fix their video that stays influencing people.
