Which programs do you actually use in your calculator?

Quora are spammers. No more, no less. I'd never heard of them and then, out of nowhere, I started receiving "Quora digest" with a mention saying "you are receiving this because you subscribed yada yada yada". No, I'm not going to "click here to unsubscribe" from something that I didn't subscribe to in the first place.

I did *not* subscribe. Quora has, however, subscribed to by blocklist.

HP50g:

PEQUM Equation Library Manager (I wish there were a source code somewhere)
Equation Solver
solve -command (usually just manipulating some basic engineering functions for ie. sanity checks)
default program editor
->tag -command
Unit conversions
TMENU with custom set of most frequently used units.
Graphing functionality to check odd curves of ie. resistor networks
I would use binary manipulation programs if there would be a good set of those (WIP some Quick and Dirty ones for personal needs)

Why? Because I do not have access to math tools (except windows calc) at work PC ...and 'they' claim that calculators are useless at this decade. Nonsense.

I usually throw together quick and dirty programs as required and delete the next time I need one.

Answers are very interesting.

On my HP35s:
- equations: TVM to simulate my 12c, RLC complex calculations, others I don't remember now
- user progs:
- P converts salary into daily rate of my consultant teams,
- B calculates their estimated bonus when they do a great job,
- M calculates the margins of my business.
All are very useful but I really miss key assignment

HP 15c:
- A: converts salary into daily rate of my consultant teams
- B: calculates their estimated bonus when they do a great job
- E: calculates the margins of my business.
- C: TVM using the built-in solver, with I for indirect addressing of variable to find
- LBL1: the true TVM formula
- LBL 0: the nice memory game found on this site

HP12c:
- 00: converts salary into daily rate of my consultant teams
- 20: calculates their estimated bonus when they do a great job

The calculator I use all the time is the HP-71B in diverse emulated forms (running on a PC, a tablet and a phone), complete with Math ROM, JPC ROM, HP-IL ROM and plenty of RAM, more than enough to have many programs instantly available, about 100+, some of them quite big.

The ones I use the most are my MINIMAX polynomial fit program (which will fit an Nth-degree polynomial minimizing the absolute errors [not the "sum-of-squared-errors"]), my IDENTIFY constant-recognition program (v2.0), and several very specific work-related programs, as all things having to do with solving polynomials, non-linear equations, integrating functions, dealing with matrices, complex numbers, Fourier transforms and number-theory functions are already taken care of by the MATH and JPC ROMs.

Very occasionally I also use an HP-15C and some SHARP pocket computers but I don't keep programs permanently stored there, I write them on the go.

Which emulators for the 71B do you use on a tablet and phone, it is Olivier's?

Yes.
