Docs for the new expressions +-*/

Summary by CodeRabbit

• Documentation
  • Added reference entries for four arithmetic functions — plus, minus, multiply, divide — each with descriptions, parameter/return details, and concrete JSON usage examples showing inputs and numeric results and null-behavior notes.
  • Updated function tables and adjusted formatting and table alignment in the expressions reference so the new functions appear consistently with availability notes for front-end/back-end.

Walkthrough

Adds documentation entries for four arithmetic expression functions — plus, minus, multiply, and divide — with definitions, parameters, JSON usage examples, numeric outputs, availability markers, and minor formatting adjustments in English and Norwegian Bokmål reference pages; Nynorsk not updated.

Changes

Cohort / File(s)	Summary
Expressions reference — English content/altinn-studio/v8/reference/logic/expressions/_index.en.md	Added public docs for plus, minus, multiply, and divide: parameter/return signatures, example JSON inputs and numeric outputs, updated function tables and availability markers, and minor formatting. (+63/-15 lines)
Expressions reference — Norwegian Bokmål content/altinn-studio/v8/reference/logic/expressions/_index.nb.md	Added localized expandable docs for plus, minus, multiply, and divide with examples and table/header formatting adjustments; documentation-only changes. (+63/-15 lines)
Expressions reference — Norwegian Nynorsk (not present) content/altinn-studio/v8/reference/logic/expressions/_index.nn.md	No changes in this PR — Nynorsk page not modified or added.

In `@content/altinn-studio/v8/reference/logic/expressions/_index.en.md`:
- Around line 313-317: The table of function parameters is inconsistent with the
detailed docs; update the parameter column entries for the functions `plus`,
`minus`, `multiply`, `divide`, and `average` so they match their detailed
descriptions: change `plus` and `minus` from "none or multiple numbers" to "one
or multiple numbers" (or "at least one number"), and change `multiply`,
`divide`, and `average` from "one or multiple numbers" to "two or multiple
numbers" (or "at least two numbers"); ensure the table text for these symbols
(`plus`, `minus`, `multiply`, `divide`, `average`) exactly mirrors the phrasing
used in their respective detailed sections.

In `@content/altinn-studio/v8/reference/logic/expressions/_index.nb.md`:
- Around line 308-312: The table rows for functions `plus`, `minus`, `multiply`,
`divide`, and `average` use invalid fragment link syntax `[Tall]($tall)`; update
each occurrence to use the correct markdown fragment link `[Tall](`#tall`)` so the
links point to the Tall section, e.g. inside the table cells for `plus`,
`minus`, `multiply`, `divide`, and `average` replace `$tall` with `#tall`.
- Around line 310-312: The parameter descriptions in the table for the functions
`multiply`, `divide`, and `average` are inconsistent with their detailed docs
(which state they expect at least two numbers); update the table entries for
`multiply`, `divide`, and `average` so the parameter column reads that they
require "minst to [Tall]" (or equivalent Norwegian phrasing matching the
detailed descriptions) instead of "et eller flere [Tall]" to keep them aligned
with the detailed descriptions.
- Around line 308-309: The Norwegian docs for the functions plus and minus are
inconsistent with the English version: update the Norwegian descriptions and the
table entries for the functions plus and minus to match the English requirement
of allowing at least one number (i.e., accept one or more arguments), not "minst
to tall"; specifically change any Norwegian phrases like "minst to tall" or "et
eller flere valgfrie [Tall]" to clearly state "minst ett tall" or "ett eller
flere tall" and ensure the parameter column for `plus` and `minus` reflects
one-or-more [Tall] arguments to match the English docs for the functions plus
and minus.

- Around line 298-316: Table parameter label casing is inconsistent: change the
"[numbers](`#numbers`)" labels to "[Number](`#numbers`)" for the `plus`, `minus`,
`multiply`, and `divide` rows so they match the rest of the table; update the
three occurrences in the rows for functions named plus, minus, multiply, and
divide to use the capitalized label.

Dette ser bra ut, men vi bør kanskje også dokumentere hvordan uttrykkene responderer på null?

1085-1127: Minor wording inconsistency across function descriptions.

The plus and minus functions use singular form "decimal or integer" (lines 1086, 1097), whilst multiply and divide use plural "decimals or integers" (lines 1108, 1119). Consider standardising to the plural form throughout for consistency, as it's slightly more natural when referring to general classes of numbers.

📝 Optional consistency fix

 {{% expandlarge id="func-plus" header="plus" %}}
-The `plus` function expects two numbers, either decimal or integer.
+The `plus` function expects two numbers, either decimals or integers.

 Example:

 {{% expandlarge id="func-minus" header="minus" %}}
-The `minus` function expects two numbers, either decimal or integer.
+The `minus` function expects two numbers, either decimals or integers.
