Sylvain Pion, Hervé Brönnimann, and Guillaume Melquiond. A Proposal to add Interval Arithmetic to the C++ Standard Library. In Reliable Implementation of Real Number Algorithms: Theory and Practice. Dagstuhl Seminar Proceedings, Volume 6021, pp. 1-25, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2006)


I will report on a recent effort by Guillaume Melquiond, Hervé Br"onnimann and myself to push forward a proposal to include interval arithmetic in the next C++ ISO standard. The goals of the standardization are to produce a unified specification which will serve as many uses of intervals as possible, together with hoping for very efficient implementations, closer to the compilers. I will describe how the standardization process works, explain some of the design choices made, and list some of the other questions arising in the process. We welcome any comment on the proposal.
