Let $\struct {S, \preccurlyeq}$ be an ordered set.
Let $a, b \in S$.
Let:
- $\closedint a b$
or
- $\hointr a b$
or
- $\hointl a b$
or
- $\openint a b$
be an interval.
The elements $a, b \in S$ are known as the endpoints (or end points) of the interval.
$a$ is sometimes called the left hand endpoint and $b$ the right hand end point of the interval.
Also known as
The endpoints can also be written as end points.
