Irrational Numbers - Math is Fun
Pi is a famous irrational number. People have calculated Pi to over a quadrillion decimal places and still there is no pattern. The first few digits look like this: 3.1415926535897932384626433832795 (and more ...) The number e (Euler's Number) is another famous irrational number.
Irrational number - Wikipedia
In mathematics, the irrational numbers are all the real numbers that are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.
Irrational Numbers- Definition, Examples, Symbol, Properties
Irrational Numbers are numbers that can not be expressed as the ratio of two integers. They are a subset of Real Numbers and can be expressed on the number line. And, the decimal expansion of an irrational number is neither terminating nor repeating. The symbol of irrational numbers is Q'.

Rational numbers are those that are terminating or non-terminating repeating numbers, while irrational numbers are those that neither terminate nor repeat after a specific number of decimal places.

Irrational Numbers
An irrational number is a nonterminating, nonrepeating decimal. 2. A few examples of irrational numbers are π , 2 , and 3 . (In fact, the square root of any prime number is irrational. Many other square roots are irrational as well.) The values of π , 2 , and 3 are shown below to 50 decimal places. (Notice the nonrepeating nature of the numbers.)
Irrational number | Definition, Examples, & Facts | Britannica
Irrational number, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals 2.
Irrational Numbers | Brilliant Math & Science Wiki
Irrational numbers are real numbers that cannot be expressed as the ratio of two integers. More formally, they cannot be expressed in the form of p q qp, where p p and q q are integers and q ≠ 0 q = 0. This is in contrast with rational numbers, which can be expressed as the ratio of two integers.
3.5: Irrational Numbers - Mathematics LibreTexts
Irrational numbers are numbers that cannot be expressed as a fraction of two integers. Recall that rational numbers could be identified as those whose decimal representations either terminated (ended) or had a repeating pattern at some point.
