 Interval (mathematics) - Wikipedia, the free encyclopedia (963 words) Interval notation is the notation in which permitted values for a variable are expressed as ranging over a a certain interval; "5 < x < 9" is an example of the application of interval notation. Intervals of type (1), (5), (7), (9) and (11) are called open intervals (because they are open sets) and intervals (2), (6), (8), (9), (10) and (11) closed intervals (because they are closed sets). Interval arithmetic, also called interval mathematics, interval analysis, and interval computation, was introduced by mathematicians in the 1950s and 1960s as an approach to putting bounds on rounding errors in mathematical computation.
