Exponential format: Engineering?

connochaetes shared this question 12 months ago

Hi.

I am aware of GeoGebra's command "ScientificText(...)". Regarding this, I'm looking for a special form: the exponential format "engineering" (in german: Exponentialformat "Technisch"). This means that the exponent is a multiple of 3. Is there an easy way to achieve this using GeoGebra?

Greetings.

I don't see an easy way :) but I'm looping your question to the Developers Team, just in case they decide to add this to the available commands ;)

Sorry, it's unlikely we'll be adding that

It is a pity that you won't be adding the option for exponential number representation.

I think just about any other scientific calculator has that feature and if you are one of the developers you know that it would be a piece of cake to implement that.

Could you please comment on why you are not offering that representation.

Is there any didactical reason to avoid the exponential representation?


As connochaetes mentioned, you'd really need that for science calculations (chemistry, physics etc..)


(And by the way: It would be IT security friendly if I wouldn't need to allow html in mails to be able to sign in with geoGebra. Especially since the great software offer is also intended for kids we should all try not to baffle kids first steps to roam the internet in a more protected way and force them back into allowing such unnecessary potential malware entry ports.)


Sorry - all in all I didn't want to sound so destructive. Great work! No ad infestation! In terms of IT hygiene, GeoGebra is lightyears better than most other stuff intended for kids.

We work on the basis of needing a good (great) reason to add a feature, rather than a reason not to.


It's a balance as there are literally 1000 things we could "easily add" :)

Hi Michael

"It's a balance as there are literally 1000 things we could "easily add"

I understand : priority for basic things : for example a MAC user can't zoom with a trackpad or a Magic Mouse with GeoGebra 5 (...)

For exponential notation, GeoGebra is a soft for Mathematics (it is always written), and it is perhaps the reason why you don't want to understand request of physicians...

(for example, you should rename the app "scientific calculator" in "mathematic calculator" because, without exponential notation (named in french "notation scientifique" or "notation ingénieur" and SCI (and ENG or ING) on CASIO or TI calculators), it is not a scientific calculator... IMO)

Sorry, I don't get your point. How many users do you estimate would benefit (or even notice) if we added ENG?

Yes. GeoGebra is used mainly by mathematicians. Physicians teachers don't use it, but when one want to use it, he needs those notations... It is basis for him... So indeed there is no many...

We are going in circles

The app "Scientific Calculator" is very nice and I use it a lot, but i understand too that a physician don"t use it (for same reason...)

May i say, how many mathematicians MACusers with TrackPad (or MagicMouse) do you estimate would benefit if you fix the zoom in GeoGebra 5..? (I know you don't like when i speak of this... but it is basis for them)

I don't fight for exotics commands, but for basis for all users... Thank's for reading.

Please keep to one bug per thread

Sorry

i give you authorization delete my answer "May i say, how many mathematicians MACusers with TrackPad (or MagicMouse) do you estimate would benefit if you fix the zoom in GeoGebra 5..? (I know you don't like when i speak of this... but it is basis for them)"

(because in this forum, users can't delete, but you can)

and you can answer your reply "Please keep to one bug per thread" and this one

(i answer in this post, because in this forum we can't sent private messages)

Thank's

Edit : and perhaps after, you can comment my answer about exponential notation, basis for physicians

Thanks for the great work of the community in this forum. Special thanks to the developers team for their great work.

@ Michael Borcherds : OK, we 'll have to deal with that.

It would have been a nice feature. Especially, students learning physics with GeoGebra would appreciate the exponential format "engineering". Obviously, it 's quite helpful for dealing with the prefixes (micro, nano, Giga, ... etc.) But it 's fine to let the GeoGebra user do this last step on by herself/himself.

create your own custom tool for creating the format in a text

@mathmagic Thank you for the idea.

Just to put things clear. Here 's some background information:

Pupils at "my" school were using "Texas Instruments Nspire CX II-T CAS" handhelds. Now, we 're starting to apply the "bring your own device" (BYOD) model: Pupils are using convertibles, tablets, ... etc. with the GeoGebra software. There are some legal issues with the usage in exams. I'm aware, that GeoGebra offers an exam mode.

So, our topics are right now: What features brings GeoGebra that are just working "out of the box" (without using custom tools)? And there 's of course the comparison to the Nspire CAS software/hardware.
