What most experimenters take for granted before they begin their experiments
is infinitely more interesting than any results to which their experiments
lead.

If we can do qd_real, we could also try using the arprec package and get
arbitrary precision math. I might be interested in that as well...
All are written as C++ types with operator overloading...

This is tricky because some C/C++ compilers long double uses 128
bits of space but actually (on Intel) only uses 80 of the bits (those
are the bits that floating point unit handles). So you do not really
get 128 bits. Also MPI may not properly handle the 128 bit doubles.
