Affine arithmetic is an extension of interval arithmetic, able to track ``the dependency between variables throughout calculations'' and to provide strict bounds. Several examples illustrate the proposed approach. Results are compared with other approaches, such as interval arithmetic, Monte Carlo simulation or solving linear systems of simultaneous equations.} }
