Állandóak

Állandóak is the plural predicate form of the Hungarian adjective állandó, used to describe quantities or properties that do not change within a given context. In mathematical and scientific language, állandó describes a fixed value, parameter, or constant that remains unchanged under specified conditions. The related noun form állandó/állandók is often used to name individual constants, while állandóak can appear in predicative sentences such as “A számok állandóak.”

In mathematics, a constant is a value that does not depend on variables in an expression or equation. Examples include numbers like π or e, and fixed parameters in a function. In differential equations, constants of integration are referred to as állandók. In physics, many fundamental constants are named values that are considered invariant, such as the speed of light c or Planck’s constant h, as well as dimensionless constants like the fine-structure constant.

In computer science, constants are values designated to remain unchanged during program execution, often declared with keywords such as const or final in various programming languages. They contrast with variables, which may change over time.

Etymology and usage notes: állandó means fixed or permanent; állandóak is the plural predicative form used when describing multiple constants. For referring to constants as a category, állandók (noun) or állandó értékek are commonly used.
