Empty Interval

3.1.2 Empty Interval

An empty interval $X =∅$ for $X ∈IR$ is defined as a singleton where

- X ={x= x= ∅}= ∅

where $∅̸∈ R$ . Hence no arithmetic can be performed on an empty interval. On a computer $∅$ is represented by qNaNs (Quiet-Not-a-Number) hence causing any arithmetic to yield further qNaNs.
