Not a double-double (which sucks IMO, as it's impossible to reason
rationally about) but Boost.Multiprecision has:
* float128: thin wrapper around __float128 and libquadmath for compilers
that support that type (mostly GCC).
* cpp_bin_float_quad: all C++ quad precision emulation, much slower than
the above, but available for all compilers.
Both have full std lib support, and work with all the Boost.Math
functions too (so all the special functions and other FP utilities).
For quadrature support see my reply to the OP.
