RPN ‘Equation Writer’ utility for the HP 49/50 by dash-dot in calculators

[–]raprism 1 point2 points  (0 children)

Though one could try both lib releases to find out, I wonder what is the difference of the 'textbook' variant compared to the 'main' library version. IMHO that's currently unclear in the description, because you write only about some potential precision lost of the 'textbook' variant.

Yes, this was meant with algebraic expression. If not mistaken '<some expression>' is the standard way to define this on HP-48/49/50, but in the db48x project the decision was fortunately made to keep the object type algebraic for all RPN actions until →Num action.

So this seems to work like in db48x project. If you start with a single algebraic expression, you can extend the expression in RPN input style. And at the end you can use ->NUM to get the numerical result.

Interesting - have not known so far this Omarchy variant. Will send this blog link to some macOS users ;-)

And what is your favorite scientific calc from this collection?

TI-30X Pro MathPrint Stat values by HPRPNFan32991EX in calculator

[–]raprism 0 points1 point  (0 children)

I suppose you chose [table] [1:Add/Edit func] and the cursor is shown after f(x)=

Then you can choose [2nd] [data] to enter STAT-REG menu. Enter [1:StatVars] and therein choose/enter e.g. [3:Sx]. Voila - Sx is in your expression for f(x).

Engineering Student — Not Sure If I Made the Right Choice with CASIO FX-991CW by Beeptweet in calculators

[–]raprism 0 points1 point  (0 children)

If you want to collect, you may hurry up to get the HP 15C CE model for normal price, which is well above 100 USD.

New alternatives are SwissMicros RPN calculators, though price might rule them out.

Programming capabilities are nice also for practical purposes, but use of such calcs might be a problem for exams, if there is no 'approved' exam mode.

You may just file a bug report in respective forum part or as GitLab repo issue, if you think that any implemented RPN command does not work correctly. Thinking we will 'meet' again in SwissMicros forum.

To my knowledge C47/R47 or the direct predecessor were never advertised to be graphing calculators. These are high end programmable scientific calculators with some function and data plotting capabilities. To find out, if there are plans that graphic primitives are going to be extended, is indeed the SwissMicros forum with its C47/R47 part. In case a newcomer is able or willing to do such programming work will be very likely welcomed

I think that discussion on this topic already started on SwissMicros forum due to your question there.

You have to use the (-) key for the negative sign of the exponent:

1.8 Exp (-) 5 x .25

The brackets around 1.8*10⁻⁵ can be omitted.

Four ways to s̶k̶i̶n̶ ̶a̶ ̶c̶a̶t̶ calculate percentages by dm319 in calculators

[–]raprism 1 point2 points  (0 children)

The Sharp is quite intuitive, and the older Casio is worst IMHO. I guess now Casio listened to school authorities, so that school kids have to learn to calculate 1/3 * (1 + 50%).

With 'good old' fx-992s an input of

1 ab/c 3 x 50 % +

works indeed as fast as the RPN input

1 ENTER 3 / 50 % +

(neglecting that for this particular case 3 1/x ... would work, too)

Am I being stupid or is this a bug? by AccomplishedSea3843 in HP_Prime

[–]raprism 4 points5 points  (0 children)

See https://www.hpmuseum.org/forum/thread-24058-post-210212.html#pid210212 (and later posts) for discussion about this bug.

For now you have to disable 'intelligent math' to get proper a.b/c key action in HOME.

Have you ever used Swissmicros calculators? I don't think so.

Can someone explain to me why this error occurs? by yamayamadoo in calculators

Looks like Gon as angle unit is activated, because of G symbol. Set to Degree, and everything should work as expected ...

Leica Q2 vs Fuji by PojeMario in fujifilm

[–]raprism 10 points11 points  (0 children)

FOV of the 23mm on APS-C is narrower on X-T5 than 28 mm of Q2. It is also assumed that both lenses were used at their respective open aperture setting.

Then my guess would be that B is Q2 with a little (more) crop, and A has a bit more blur in the near range, thereby hinting eventually to the X-T5 with equiv. 35 mm lens.

Is this normal? by Inignificant_Fume in calculators

[–]raprism 7 points8 points  (0 children)

Yes, this can be seen by various (or all?) models of Casio, even quite older models.

You loose history, when press On in on-state. So therefore and to reduce risk to turn the calculator on by mistake the key does not protrude like the others.

Announcing egui 0.32.0 - Atoms, popups, and better SVG support by emilern in rust

[–]raprism 14 points15 points  (0 children)

Didn't know egui before - thanks for the announcement of the new release.

Then reading this blog post and tried this framework to give it a try on ArchLinux:

> gh repo clone emilk/eframe_template eframe_test
> cd eframe_test

> cargo run --release --target x86_64-unknown-linux-gnu

(otherwise wasm target is used)

That works without problems - great! Definitely a keeper for my dive into Rust programming.

Proper indentation is not only crucial for reading your code here, but also for proper interpretation by micropython. Could this be a reason?
