rating setting

This setting specifies an optional rating for a formula or class, which is shown in the browser. As a formula author, you can use the rating setting to let users know which formulas they should try first, and which are not generally useful. There are three possible values:

recommended
Use this for the most useful formulas in your files, so people who try your formulas know where to start.
average
This is the default category for formulas that do no include a rating setting. These formulas are useful, but perhaps not the best ones to start with. For example, they could be intended for specific purposes only instead of being generally useful.
notRecommended
You could use this for formulas that have been superceded by other, more powerful formulas, or for formulas that contain flaws which you cannot address for backwards compatibility reasons.

If the rating setting is not included, it defaults to average.

This setting can be used in the default section of transformations, fractal formulas, coloring algorithms, and classes, and only affects how the browser displays the formula or class.

To include the rating setting while keeping your formula compatible with Ultra Fractal 4 or earlier, test for the VER50 symbol as shown in the example below.

Example:

default:
$IFDEF VER50
  rating = recommended
$ENDIF
