| ==Rationale== |
|
| ===Use cases=== |
| * Superscript |
| ** Basic maths |
| ** Units of measurement (e.g. square meter - m²) |
| ** Large numbers, metric scientific notation (e.g. 1,253x10²³) |
| ** Ordinal numbers (e.g. 1^^st^^, 2^^nd^^, 18^^th^^ century, in French 1^^er^^, 2^^e^^, 18^^e^^ siècle) |
| ** Possibly for footnotes (shouldn't it be handled by another mechanism than what is considered, in that particular case, as a presentation markup) |
| ** Many indexed terms in science (like n^^+^^) |
|
|
| * Subscript |
| ** Basic maths |
| ** Basic chemistry |
| ** Much of biology (gene names, etc.) |
|
| ===Alternatives=== |
| * Unicode digits |
| * Specialized markup languages like MathML, ChemML and LaTeX |
| than as part of formulas. |
|
| ===Advantages=== |
| * Simple way to insert superscripted/subscripted text |
| * The users don't have to learn a new language. |
| * Super- and subscript are basic functions in most word processors |
| * Super- and subscript almost always have a semantic value, rather than being a formatting issue. |
| * Depending on the software/keyboard layout, it might be very difficult or impossible to insert Unicode superscript or subscript digits. |
| * Unicode digits: |
| ** are limited to... digits! - thus covering only a small subset of use cases (⁽⁻ⁱ⁺ⁿ⁾⁼°ₔ₍ₐ₊ₑ₋ₓ₎₌ₒ) |
| ** The presentation of successive Unicode digits is not always appropriate (see above of this source). |
| * MathML etc. is necessary for specialized applications, especially in Math. However: |
| ** Complex formulas were historically expensive, and use in engineering and science therefore limited. Invention of symbols involving the no-cost super and subscript was much more frequent. |
| ** In practive, MathML etc. is not currently supported, and does not correspond with the frequency of use of super- and subscript in engineering and science. LaTeX is, on the other hand, more common and known to many publishing in physics, engineering, or math (but few inther sciences). |
| * LaTeX is rendered very poorly in browsers which do not have built-in support for MathML, typically with coarse raster images, and font, size and aliasing mismatch. |
| * Inline with [Cover the common things people need|Goals] (is it?) - Yes! |
| * NotNew, a lot of wiki engines offer markup for superscript and subscript text. HTML offers it. But uses different markup. |
|
| ===Disadvantages=== |
| * Better alternatives exist |
| ** Please elaborate which alternatives are available in which Wiki software |
| ** Wiki engines supporting LaTeX includes: [[MoinMoin]], [[Oddmuse]], [[MediaWiki]], ... (add more) |
| ** Wiki engines supporting image inclusion: practically all |
| ** Wiki engines supporting simple ways to insert unicode characters/images (smileys): [[MoinMoin]], [[Oddmuse]], ... (add more) |
| ** New markups to learn -- NotNew though. |
| * Users who already use the standard markups have to learn a yet another one. |
| * Markup characters can be hard to find on several keyboard layouts. |
| * The markup is hardly readable. |
