Examples/Parameter: format (example 2)

Example
The following is an example of how to use the variable  to set the font size. This will list articles in Category:Fruit examples, by title (in descending order), limited to a count of four. Each result will be formatted to appear on a new line and the font size will be set using a parser function (math) expression, to calculate the current article sequence number (starting from 1) times 0.5em, which will increase the font size each subsequent article.
