- Name
intervalClosureType- Definition
- The closure conditions of the two endpoints of a numeric interval.
- Description
- Interval endpoint notation uses the parenthesis to specify that the endpoint is excluded from the interval (the continuous interval extends to, but does not include, the endpoint) and the square bracket to specify that the endpoint is included in the interval (the continuous interval extends to and includes the endpoint). For example, the unbounded interval [lowerValue, +infinity) where the lower endpoint is included and there is no upper endpoint.
