In mathematics, the adjective constant means non-varying. The noun constant may have two different meanings. It may refer to a fixed and well defined number or other mathematical object. The term mathematical constant (and also physical constant) is sometimes used to distinguish this meaning from the other one. A constant may also refer to a constant function or its value (it is a common usage to identify them).
