Work is already underway in the C++ committee on the following Work Item:
"JTC1.22.24733 - ISO/IEC TR 24733 - Information Technology - Programming Languages C++ - Technical Report of Type 2 on Extensions for the programming language C++ to support decimal floating point arithmetic"
The latest draft of this document is not yet on the WG21 committee website, but I imagine that it will be very soon. You can see an older draft there now: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2005/n1839.html
The current mailing just became available. The latest version of the decimal arithmetic proposal is http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n1965.html Stefan (or others), would you have any interest in implementing this proposal for Boost (under the Boost license)? Although it would be a big job, the critical interface design and documentation work are essentially done in that you can just reference Robert's paper. It would a useful library for Boost users, and any issues you ran into would illuminate areas of Robert's proposal that needs more work. The resulting improvements would be of long term benefit for C++. --Beman
