There is ISO/IEC TR 24733 draft on decimal floating-point arithmetic. I found old thread by Stefan Slapeta: Decimal floating point library [1] I wonder, what is status of this idea in Boost?
I don't think anyone in Boost is working on it (that I know of) - it appears there was a C++ reference implementation available on the IBM website, but it looks like it might have been removed :-( In the mean time, some of us have been working on extended precision arithmetic (see "big_number" directory in the sandbox) using Christopher Kormanyos' e_float code for decimal arithmetic. Now that I've been reminded of IBM's C lib reference implementation of decNumber, I'll add support for that as well.... could make a good test case. Regards, John.
