In mathematics, the adjective constant means non-varying.
The noun constant may have two different meanings.
Fixed number
A constant is 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.
Constant function
A constant function or its value (it is a common usage to identify them).
Such a constant is commonly represented by a variable which does not depend on the main variable(s) of the studied problem.
This is the case, for example, for a constant of integration which is an arbitrary constant function (not depending on the variable of integration) added to a particular antiderivative to get all the antiderivatives of the given function.
