I'm having a problem with decimal fractions in a numerical question in the lesson module. In Poland, we write fractions with commas, rather than dots. So, instead of 0.5 we write 0,5. However, fractions written with commas are not interpreted as fractions. Is there a way to "tell" Moodle that it should treat 0,5 as a fraction?

This should just work, and if it does not, it is a bug because UK/US/Aus developers did not consider it. The some of the corresponding bugs in the quiz only got fixed recently.

Thanks for the screenshot, but ... in order for me to copy-paste your questions text and answers on my own moodle test site to check it out I need text, not a picture.

Answer: 176,71
Feedback: To jest poprawna odpowiedź
The course author's intention is to only accept a precise answer (176,71), with no tolerance. However, apart from the correct answer, some other answers are accepted as well, e.g.:
- 176
- 176,2
- 176,999
The feedback is always displayed like this:
Your answer : 176

It seems as if Moodle is ignoring anything that comes after a comma.

OK, Przemyslaw, I could reproduce the bug.
Indeed, unlike the Quiz numerical question, the Lesson numerical question does not take into account the various countries' way of displaying the decimal separator.
I will enquire and report here.

Can you try the attached patch (against moodle 2.3, but should be the same on 2.2) on a test site?
It seems to do the trick. If reports are favourable, I'll open a bug report.

Hello Joseph,
We have the same issue with our moodle installation (version 2.4.1+). Could you please tell me if you intend to introduce this patch in future versions of moodle ?
Thanks,
Patrick

@Patrick,
I was waiting for the OP to confirm that it worked... but he never replied.
I have now reported this (with a fix) as MDL-40227 for which you can vote. However, please note that I am not in a position to make changes to the Moodle core distributions, so we'll have to wait for a Moodle HQ developer to do it.
