Event field annotation to use on fractions, typically between 0.0 and 1.0, to specify that the value is a percentage.

For example, a field with the value 0.5 annotated by this annotation, should be interpreted as 50% and rendered in a graphical user interface with a percentage sign to avoid confusion with 0.005%.

Since:9
