![]() Real numbers are the combination of rational and irrational numbers. If you combine the set of rational numbers and the set of irrational numbers, the resulting set is the set of real numbers. For instance, the famous pi (π) which is used to calculate the circumference of a circle and the value of which is approximately 3.1416… is an irrational number. There are a lot of important irrational numbers in mathematics. Irrational NumbersĪ number that is not a rational number is an irrational number An irrational number cannot be expressed as a fraction with integers.Įxamples of irrational numbers are the non-terminating non-repeating decimals such as 0.321315325453… Using this example, you cannot provide two integers such that when you divide the first integer by the second integer, the result will be 0.321315325453… For example, in 0.9292… the number 2 is not the last digit of the decimal number since there are digits that follow 2. A decimal with an ellipsis means that there are digits that follow after the last digit of the number. Note: The “three-dot” symbol that is used on some decimals is called an ellipsis. You cannot express these non-terminating non-repeating decimals as a fraction with integers. Non-terminating non-repeating decimals have an uncountable number of digits that are not repeated in a certain pattern. Meanwhile, non-terminating non-repeating decimals such as 0.5411346565134…, 0.28992139813…, etc are not rational numbers. ![]()
