There are German standards documents for typesetting of math and science. As far as I can tell, of particular interest are DIN 1304 (symbols in formulas) and especially DIN 1338 (typesetting of formulas).
As there are packages for citing according to German citation rules (DIN 1505), namely
dinat, I was wondering whether there are also packages facilitating German-style mathematical typesetting.
(I understand that some of the German traditions cannot be automated and are left to the authors. Examples, for those who are interested: We don't use the ∴/∵ symbols nowadays (even though they seem to have originated in Germany), we always use centered dots (and never
\times) for multiplication in arithmetic, we don't write things like "3(4)(5)=60" (found in many US textbooks, though not at the university level), and we use "~" instead of "∝" to indicate proportionality between two physical quantities. As for these examples, I do not know to what extent they follow from DIN 1338.)
An example given by a relevant German Wikipedia article would be that in German math typesetting, limits always appear below/above a sum symbol, though (disclaimer!) I have not verified this statement against the standard DIN 1338.
