Hi,
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?

Sadly the GPL license put a blocker on using any of IBM's code inside Boost, as was noted by several people at the time
Trying to understand this situation around decNumber and its derivatives: There is C library decNumber which has been released by IBM under ICU License (X/BSD-like?). The decNumber is included in GCC [1]. Next, the C++ library decNumber++ was based on the decNumber and implemented ISO/IEC TR 24733 interface [2]. Strangely, it seems [3] the decNumber++ was released under terms of more restrictive license, GPL. I understand ICU License is not the same as Boost Licence, so copying decNumber.c|h is not possible, but perhaps it is possible to have a student who reimplements Boost.Decimal from scratch and with "inspiration" (grey area?) from decNumber.c|h [1] http://gcc.gnu.org/svn/gcc/trunk/libdecnumber/ [2] Listed at IBM developerWorks but download is missing http://goo.gl/mOqSI [3] http://www.ibm.com/developerworks/forums/thread.jspa?threadID=151629&tstart=0 Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
