Extend formula handling to cope with actuarial notation

Problem:
I'm looking to improve the formatting of actuarial notation on Wikimedia sites. The most important bit that is missing from the current capabilities is the angle notation used to denote a period of years (but there are other features of the notation which are also difficult to implement). In the example image to the right, it's the angle over the 'n' that is marked as '3'.
Our current workaround is to use a separate horizontal and vertical line, thus: $A_{x:{\begin{smallmatrix}\hline ~n|\end{smallmatrix}}}$ . But it's a poor workaround, as you can see.
Proposed solution: There is a TeX extension that provides all the required functionality for actuarial notation: actuarialsymbol. Adding this (or a similar equivalent package) to the Wikimedia installation solves the problem.
Who would benefit: Users reading and writing about actuarial mathematics.

Support The only proposal which has anything to do with mathematics. (I was looking for a proposal, which enables mathimatical operations in a Wiki table. I haven't found one. This was the closest. Therefore I wote on it.) Editor Pirate (talk) 10:11, 12 February 2023 (UTC)[reply]
