Comment (by anonymous):

 For decimal floating point types it *may* stream out 2 digits too many -
 we should really be using C++11 max_digits10 and not digits10+2 - actually
 that could be fixed by checking for BOOST_NO_CXX11_NUMERIC_LIMITS and
 using max_digits10 when not defined and digits10+2 when it is.

 For fixed point decimal the floating point code will '''not''' be
 triggered: these don't have a floating point (max_exponent is zero), and
 are generally regarded as "exact" in the same sense that integers are
 exact albeit truncating.

 You're right about special types often not having std lib support - though
 typically that's a transitional thing when they're first introduced?
