Small module helps to display the numeric integer field as numeric versions by enabling the version field Formatter,

For example

You need to create a content type which needs to have simple versions to integrate with third party service.

You can just create a simple integer field either you get version numbers from users (content authors/admin) or you can increment version when the content is been saved by using hook_entity_presave and in the formatter if you enable the version the numbers will be displayed as versions
