![]() Whole numbers represent entire objects with no pieces or fragments. Whole numbers include the subset of natural numbers. For example, the following numbers are integers:Ī whole number is a positive whole number with no fractional or decimal part. Integers include the subsets, whole numbers, and natural numbers. The natural number 1 is a rational number you can express with the fraction 1/1.Īn integer is a positive or negative whole number with no fractional or decimal part. The whole number 32 is a rational number you can express with the fraction 32/1. The integer -4 is a rational number you can express with the fraction -4/1. The decimal 0.33 is a rational number you can express with the fraction 1/3. The decimal 1.5 is a rational number you can express with the fraction 3/2. For example, the following numbers are rational numbers: Rational numbers include integers, whole numbers, and natural numbers. The golden ratio is another decimal with no end and no discernable pattern.Ī rational number is a number you can write as a ratio of two integers, or a simple fraction. The square root of two is another never-ending decimal.Įuler's number is a decimal with no pattern or end. The number pi is a decimal that goes on forever without repeating and you cannot write it as a fraction. For example, some known irrational numbers are: Numbers that you cannot write as a fraction are decimals that go on forever with no repeating pattern. Irrational numbersĪn irrational number is a real number you cannot write as a simple fraction. There are five categories of real numbers you can define to understand integers and real numbers: 1. Related: 20 Jobs in Math to Explore Categories of real numbers ![]() ![]() The real number series includes natural numbers, like counting or whole numbers, integers, like positive and negative whole numbers including 0, rational numbers, like fractions, and irrational numbers, such as irrational or nonrepeating decimals. Integers follow the set of natural numbers, such as 1, 2, 3, and 4, and both sets include counting numbers, like 0. Integers refer to a set of whole and natural numbers that include zero and negative whole numbers, which can be positive or negative, including 0, -1, -2,–3,–4, and–5. Integers and real numbers are two separate categories of numbers, where integers belong to the subset of rational numbers, and real numbers include all irrational and rational numbers. If you want to understand the nature of the two types of numbers, you may benefit from comparing integers versus real numbers. In this article, we compare integers versus real numbers, discuss real numbers categories, review the characteristics of integers, explore how integers and real numbers differ, share their importance, provide examples of how to use both, and provide tips on using these numbers. Real numbers and integers belong to two distinct categories of numbers, and understanding the difference can help you learn about number systems. Some of these categories overlap and include subsets because they have similar characteristics, while others are unique with no overlap. Categories of numbers show how some groups of numbers are like other groups of numbers. ![]()
