Adobe Exam AD0-E123 Topic 1 Question 9 Discussion

In HTL, the format option in the data-sly-use or data-sly-test attribute can be used to format values according to a pattern. The pattern '-#.##%' indicates that the number should be formatted as a percentage with up to two decimal places. The piValue variable would be the number to format, and in this example, it would convert -3.14 to -314%. The @ symbol is used to denote the use of an option with the variable in HTL.

Options B and C are incorrect because they do not use the correct syntax for the format option in HTL. The use of @ is to specify options and not part of the variable or pattern itself.
