Hello, today I discovered that punctuation marks following a formula with display=block are rendered on the next line. I think that's wrong.

Christian1985 added a comment to T268935: Create a bot that replaces :<math with <math display=block.

@Esanders , in the German Wikipedia, the formula is centered rather than just slightly indented. Is this because of my settings? I find the centered display a bit unusual.

Christian1985 added a comment to T268935: Create a bot that replaces :<math with <math display=block.

I think that if we replace :<math with <math display=block, the indentation of the formula will be lost. But we should keep it. Is there actually a better way to indent a formula than using a colon?

Christian1985 added a comment to T382267: Math block inside a {{blockquote}} render in display style in MathML and Client side MathJax.

Hello,

I added also T375238 as a parent task. I think this is also the problem seen in the picture

image.png (650×1 px, 71 KB)

The picuture is gereated from https://de.wikipedia.org/w/index.php?title=Integralrechnung&oldid=259297415 And I used MathJax for rendering.

The code is:

Stammfunktionen und der Hauptsatz der Differential- und Integralrechnung

{{Hauptartikel|Fundamentalsatz der Analysis}}Die Integration ist eine nicht-eindeutige Umkehrung der Differentiation. Um dies zu präzisieren, wird der Begriff der [[Stammfunktion]] benötigt: Ist <math>f</math> eine Funktion, so heißt eine Funktion <math>F</math> eine ''Stammfunktion'' von <math>f</math>, wenn die [[Differentialrechnung|Ableitung]] von <math>F</math> gleich <math>f</math> ist:
: <math>F' = f</math>

Christian1985 added a comment to T420394: MathJax Rendering or MathMl rendering of \overset \prime is wrong.

@Physikerwelt , I'm not sure. I removed the space from the german Wikipedia page and the formular looks okay. So there is no priority to fix the bug. But I think it is a bug. In a way it would be nice to document the bug, but at the moment I see no need to fix it.

Christian1985 added a comment to T375238: Client-side MathJax rendering problems.

Hello @Physikerwelt ,

yes I would say, that smallmatrix should be a bit smaller. Smallmatrix can be used inline and therefor ist to big. The fraction should also be adjusted. Not only is the c too small, but so is the first two. The fraction looks very ugly.

Thank you for adding the smallmatrix problem. Was the issue with the c resolved?

I think in the formular
:<math>\int\limits_{V} (\phi(\vec{r}\,') (-4\pi \delta(\vec{r} - \vec{r}\,')) - \frac{1}{|\vec{r} - \vec{r}\,'|} (-4\pi \rho(\vec{r}\,')))\, \mathrm{d}V' = -4\pi\int\limits_V \phi(\vec{r}\,') \delta(\vec{r} - \vec{r}\,') \, \mathrm{d}V' + 4\pi \int\limits_V \frac{\rho(\vec{r}\,')}{|\vec{r} - \vec{r}\,'|} \, \mathrm{d}V'</math>.
is the same error.

Christian1985 added a comment to T375238: Client-side MathJax rendering problems.

The new MathJax rendering appears somewhat more compact in its layout. Within running text, this generally results in a cleaner and more aesthetically pleasing presentation. However, in the sections on functional analysis and tensor analysis—both subfields of mathematics—formulas frequently contain a large number of indices, including nested indices. In the more condensed format, these expressions have become noticeably harder to read.

Christian1985 added a comment to T375238: Client-side MathJax rendering problems.

yes I would say, that smallmatrix should be a bit smaller. Smallmatrix can be used inline and therefor ist to big. The fraction should also be adjusted. Not only is the c too small, but so is the first two. The fraction looks very ugly.
