-- | double-double and quad-double number type via libqd
--   
--   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.
--   
--   <tt><a>Numeric.QD.DoubleDouble.DoubleDouble</a></tt> and
--   <tt><a>Numeric.QD.QuadDouble.QuadDouble</a></tt> are strict tuples of
--   <tt>CDouble</tt>s, with the following instances:
--   
--   <ul>
--   <li><pre><a>Eq</a></pre></li>
--   <li><pre><a>Floating</a></pre></li>
--   <li><pre><a>Fractional</a></pre></li>
--   <li><pre><a>Num</a></pre></li>
--   <li><pre><a>Ord</a></pre></li>
--   <li><pre><a>Real</a></pre></li>
--   <li><pre><a>RealFloat</a></pre></li>
--   <li><pre><a>RealFrac</a></pre></li>
--   <li><pre><a>Show</a></pre></li>
--   <li><pre><a>Storable</a></pre></li>
--   </ul>
--   
--   But note that the following functions (while present) are
--   <tt><a>undefined</a></tt>:
--   
--   <ul>
--   <li><pre><a>properFraction</a></pre></li>
--   <li><pre><a>truncate</a></pre></li>
--   <li><pre><a>round</a></pre></li>
--   <li><pre><a>decodeFloat</a></pre></li>
--   <li><pre><a>encodeFloat</a></pre></li>
--   <li><pre><a>exponent</a></pre></li>
--   <li><pre><a>significand</a></pre></li>
--   </ul>
--   
--   Non-crashing implementations of these are planned in a future update
--   to this package, as well as instances of <tt>Enum</tt> and
--   <tt>Read</tt>.
--   
--   Additional note: libqd depends on 64bit doubles, while some FPU
--   architectures use 80bit. It is highly recommended to compile with
--   -fno-excess-precision and set the FPU control words to avoid erroneous
--   behaviour, perhaps by doing something like this at the start of your
--   program:
--   
--   <pre>
--   import Foreign (nullPtr)
--   import GHC.Conc (forkOnIO, numCapabilities)
--   import Numeric.QD.FPU.Raw (fpu_fix_start)
--   main :: IO ()
--   main = do
--     mapM_ (flip forkOnIO $ fpu_fix_start nullPtr) [ 0 .. numCapabilities - 1 ]
--     -- ...
--   </pre>
