This package supports both a double-double datatype (approx. 32
decimal digits) and a quad-double datatype (approx. 64 decimal
digits). The computational library is written in C++. Both C++ and
Fortran-90 high-level language interfaces are provided to permit one
to convert an existing C++ or Fortran-90 program to use the library
with only minor changes to the source code.
