Description (last modified by was)

This would be like the RealDoubleField? in rings/real_double.pyx or like riungs/real_mpfr.pyx, except that the quad double library is a C++ library -- so actually this might be similar to the Givaro wrapper in rings/finite_field_givaro.*.

The quaddouble library (and docs?) are available at

Also, I made a SAGE package, which you get by doing

    sage -i quaddouble-

Feel free to correct me.
