Title: EROC: A Maple Library for Exact Real Object Computation Authors: G. Bodnar, J. Schicho Affiliation: RISC-Linz, J. Kepler University, Linz, Austria Abstract: The EROC package implements computable real numbers and related objects in Maple. It is meant to be a tool that can be used in symbolic-numeric computation. The main topics we discuss are: representation and arithmetic of exact real numbers, vectors and matrices; polynomial arithmetic and root computation. Some operations raise ill-posed problems; we used regularization methods to solve them.
