The value of this read-only custom field is dynamically calculated from a custom mathematic or numeric expression.
It can be used to obtain a numeric value depending on the value of other fields in the current issue or in any other issues (linked issues, sub-tasks, epics, stories, JQL selected issues, etc).
Configuration
Configuring a Smart number field is straightforward. You have to configure a valid expression, which will "calculate" the output, and optionally define a custom display format.
