On Design and Implementation of a Generic Number Type for Real Algebraic Number Computations Based on Expression Dags

We report on the design and implementation of a number type called Real_algebraic. This number type allows us to compute the sign of arithmetic expressions involving the operations . The sign computation is always correct and, in this sense, not subject to rounding errors. We focus on modularity and...
