CONSTANT – Cambridge English Dictionary
Wikipedia Definition
In mathematics, the word constant conveys multiple meanings. As an adjective, it refers to non-variance (i.e. unchanging with respect to some other value); as a noun, it has two different meanings: A fixed and well-defined number or other non-changing mathematical object, or the symbol denoting it. The terms mathematical constantor physical constant are sometimes used to distinguish this meaning.
