Exact real computation allows many of the advantages of numerical computation (e.g. high performance) to be accessed also in symbolic computation, providing validated results. In this paper we present our approach to build a transparent and easy to use connection between the two worlds, using this paradigm. The main discussed topics are: representation of exact real objects, operations on exact real matrices, polynomial greatest common divisor and root computation. Some of these problems are ill-posed; we use regularization methods to solve them.
