| ### 3.3.4 Coefficient rings SINGULAR supports coefficient ranges which are not fields, i.e. the integers and the finite rings for a number `n`. These coefficient rings were implemented in SINGULAR 3.0.5 and at the moment only limited functionality is available. ### p-adic numbers The p-adic integers are the projective limit of the finite rings for `n` to infinity. Therefore, computations in this ring can be approximated by computations in for large `n`.
