Version 4.9 for Moodle 3.0 to 3.8 is now available.

David,

Thank you for trusting me and entrusting me with the maintenance of the Formulas plugin.

Jean-Michel has done remarkable work for many years as the maintainer not only of the Formulas plugin but also of many others. I and many other moodlers owe him a lot. Now that he's taken a well-deserved retreat, I wish him health, happiness and good times in his beautiful rooftop terrace in Montpellier, in the south of France.

The maintenance of this wonderful plugin, brilliantly written ten years ago by Hon Wai Lau, is truly an honor for me, and a task that I will strive to carry out as best as possible.

is it possible to assign a negative feedback to a wrong answer, as for example in the multiple choice question?

It is great to hear that the plugin got a new maintainer, Dominique Bauer. I expected his works would keep the plugin alive, and this would benefit for many teachers and students.

It takes years of my work to finish the core part of the plugin, and many more years of work from Jean-Michel to port and maintain it in the new version of Moodle. Let me take this time to thank him for his great work again.

Can I install formula's plugin on Windows server ?
I requested the installtion of stack plugin previously , but turns out It isn't supported on Windows .

Does the relative error variable in grading criterion accept "== 0"? We tested a simple multiplying and division question with the Number answer type, and the correct answer was marked as incorrect in the preview window - seemingly randomly. The problem vanished when we switched the grading criterion to "Relative error < 0.001" or "Absolute error < 0.000001. Is this a bug or working as intended?

The random variables we used were:
firstthing={16,24,28,32,48,56,64};
secondthing={8,10,20,40}

The global variables we used were:
answer=(4*firstthing)/secondthing*7

Thanks so much for this great plugin! Might I suggest two features?
1) It would be great to have a function to return the number of significant figures of a number.
2) To me, it would be helpful to fix an absolute number of points to be deducted in case of wrong units instead of a relative amount.
Thanks for considering..!

I have switched to Marklar editor in order to properly save JSXGraph code in Formulas questions (it gets overly sanitized by Atto HTML editor). Strangely, Markdown input does not seem to get parsed as Markdown but rather HTML in Formulas questions, whereas it is parsed as Markdown in other activities. Can you confirm this?

It would be useful to integrate the script that resizes text boxes while users are typing (see https://moodle.org/mod/forum/discuss.php?d=390574) in a new version of the plugin. Maybe with a check box in the question creation form : Auto resize (Yes/No).

I would like to make a small suggestion for a future version: It would be nice to select scientific notation for the correct result, which is shown as feedback.

I was trying to look up how to resize the answer box on the https://moodleformulas.org/ site and the login appears to be stuck in a loop. Could you please check this. Thanks!

Hi guys,

first of all: This qType is amazing! I came across this qtype just recently and I am currently migrating all of my static questions to the formula type.

However, I just experienced an issue while trying to regarde a quiz. After the quiz was taken by the students I realized that I was to strict in terms of rounding tolerance. So I modified the "relative error" setting in the question and performed a regrading. However, the regarding shows no effect on the automatic grading nor the display of the "correct answer" (also adjusted). Do I have to reset or change any other setting to impact the marking in the regrading process?

Cheers
Daniel

Hi
It seems that when the answer is a number answer, any text (non numeric for exemple) should show an alert. It's usefull for the comma decimal alert for french people...
But it seems that it doesn't work anymore.
- Tested on your site (and mine) : https://moodleformulas.org/course/view.php?id=22&section=4
- Tested on Firefox and Chrome
When in the answer box you write something else than number, no alert shown and aswer considered as wrong.
Did I misunderstood ?
