👉 The term "unheppen" is typically used in mathematical notation and programming languages to represent a number that is not considered a real number. It is often used to denote an irrational or transcendental number, such as pi (π) or e (Euler's constant), which are numbers that cannot be expressed exactly as decimals or fractions. In mathematical terms, it can also mean a number that is not rational or algebraic and does not have a finite decimal representation.
