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

http://www.cs.berkeley.edu/~yozo/

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

    sage -i quaddouble-2.1.213.1.spkg

Hello,

I assume this has been done, due to the fact that we have

-rw-r--r--  1 mabshoff mabshoff   3592 Jun 30 09:09 real_rqdf.pxd
-rw-r--r--  1 mabshoff mabshoff  49291 Aug 18 06:41 real_rqdf.pyx

in sage-2.8.2.rc3/devel/sage/sage/rings.

Feel free to correct me.

Cheers,

Michael
