I added two use cases to the wiki page:
Formatted number control
In some cases you want to format the number in the UI, but store it as decimal in your instance. The most common case is a thousand separator (user should be able to leave out the thousand separator, but after exiting the field the thousand separator should be added), but there are more exotic cases e.g. negative numbers by surrounding number with parenthesis.
Currency input control
In some cases a currency symbol should be automatically added to the input control but it shouldn't go in the instance (in the instance the value is a decimal)
