The qd package
This package supports both a double-double datatype (approx. 32 decimal digits) and a quad-double datatype (approx. 64 decimal digits), using libqd (which is implemented in C++ with C and Fortran wrappers). To compile this package you need libqd to be installed.

CDoubles, with instances of:
Additional note: libqd depends on 64bit doubles, while some FPU architectures use 80bit. When using the Unsafe modules this might cause erroneous results; the Safe modules (used by the instances above) set and restore the FPU flags in foreign code to avoid race conditions from pre-emptive Haskell threading.
instances have been removed in this release as they were
