The Greatest Integer Function The Greatest Integer Function Greatest Integer function as the name suggests does the greatest integer number that exists in the number. Simplifying the words, we can say that it is the integer number lesser than or equal to the given number. It is represented by [number] (“big bracket”). Now the question arises that in which case it will be equal to the given number, and in which case it will be lesser than the given number. So it is quite obvious from the definition that, if we have to find the greatest integer function for an integer number then it will be equal to the given number and if we have to find for a non-integer number then the integer part of it will be the greatest integer function of it. We can say that the greatest integer function of a given number is the closest integer number on the number line to the left of the given number. Know More About : Ordering Fractions Calculator

The domain of the greatest integer function is the set of real numbers which is divided into a number of intervals like [-4, 3), [-3, 2), [-2, 1), [-1, 0), [0, 1), [1, 2), [2, 3), [3, 4) and so on. Hint: [a, b) is just an interval notation which means a ≤ x < b, where x is a real number in the interval [a, b). When the interval is of the form [n, n + 1), where n is an integer, the value of the greatest integer function is n. For example, the value of the greatest integer function is 4 in the interval [4, 3). The graph of a greatest integer function is not continuous. For example, the following is the graph of the greatest integer function f (x) = |_x_|. The GIFRP has several admirable objectives. It offers a free online version of the latest draft on the Full Text page. This way, our work is periodically updated as a paperless edition. It includes an exercise set so that the material can serve as a 'green course' for undergraduate students where they would learn number theory and analysis. The exercise set would be mailed to professors who volunteer to teach a course or offer a private study on it for free. Our next goal for the GIFRP is to include a small volunteer board headed by a PhD that would handle day-to-day administrative work and conduct research to discover new objectives and improve the Full Text and exercise set.

We would also like to expand the coverage of number theory topics so that this work could pass for a first-semester course on the subject; it is already near that point. This work is a must-read for anyone interested in learning more about integers. In fact, our highest objective in our study of the greatest integer function is using it to express a variety of concepts and statements involving integers (such as in number theory, discrete math, and analysis) mathematically so that we can work with them on a more solid foundation. We have good reason to believe that with sufficient study of the greatest integer function we can achieve this objective. We can use the greatest integer function to express the integer and fraction parts of any real number in terms of itself. Since the greatest integer function is continuous in the sense that its domain includes all real numbers and discrete in the sense that its range is restricted to integers, the greatest integer function acts as a bridge between the continuous and the discrete by sending any real number to the nearest integer that does not exceed itself. And while number theory is the study of properties of integers, the study of the greatest integer function is the study of properties (and applications) of integer functions. For these reasons, the study of the greatest integer function is indispensable to our understanding of integers.
