👉 Irregularity or irregularity, also known as irrationality, is a philosophical concept that refers to an idea that certain mathematical concepts and properties are not rational or predictable. It suggests that natural numbers (such as 1, 2, 3, 4, etc.) are not the same as integers, which are rational numbers. Irregular numbers include non-rational numbers like pi (π), e, and square roots of irrational numbers such as √4 and √5.
