In mathematics, a (real) interval is a set of real numbers that contains all real numbers lying between any two numbers of the set. For example, the set of numbers x satisfying 0 ≤ x ≤ 1 is an interval which contains 0, 1, and all numbers in between. Other examples of intervals are the set of numbers such that 0 < x … See more An open interval does not include its endpoints, and is indicated with parentheses. For example, (0, 1) means greater than 0 and less than 1. This means (0, 1) = {x 0 < x < 1}. This interval can also be … See more The interval of numbers between a and b, including a and b, is often denoted [a, b]. The two numbers are called the endpoints of the interval. In … See more Intervals can be associated with points of the plane, and hence regions of intervals can be associated with regions of the plane.
