Usage[edit]
This template produces the notation for f-number, stylizing the f as a script 'f/' as is common in photography.
This template accepts up to 2 unnamed parameters, to create an f-number such as {{f/|2}} → f/2, or an aperture range such as given for variable-aperture zoom lenses:
{{f/|4|5.6}} → f/4–5.6. When a second aperture parameter is provided, the range is separated by an en-dash (in accordance with MOS:NUMRANGE).
Examples[edit]
{{f/}}→ f/{{f/|2}}→ f/2{{f/|4|5.6}}→ f/4–5.6{{f/|#}}→ f/#{{f/|#|link=y}}→ f/#
Accessibility note[edit]
This template emits a standard f character that is stylized with CSS in order to discourage use of visually-stylized, but incorrect or inaccessible, alternatives such as:
- 𝑓, "Mathematical small f" (Unicode U+1D453);
- ƒ, "Latin Small Letter F with Hook" (U+0192) – often misused by Mac keyboard users (⌥ Opt+F) for being easy to type, and visually similar to the previous character;
- f,
{{mvar|f}}; - ,
<math>f</math>.
Note that the last two examples above are read as the character 'f' by screeen readers.
The entire output content is wrapped in a <span>...</span> HTML tag for semantic purposes, fallback copy/paste, and screen reader recognition for accessibility.
