<p>
      There are a small number of performance tuning options that are determined
      by configuration macros. These should be set in boost/math/tools/user.hpp;
      or else reported to the Boost-development mailing list so that the appropriate
      option for a given compiler and OS platform can be set automatically in our
      configuration setup.

                used by this library are integers. Normally these are stored as tables
                as integers, but if mixed integer / floating point arithmetic is
                much slower than regular floating point arithmetic then they can
                be stored as tables of floating point values instead. If mixed arithmetic

                "2" in that the code is carefully ordered to make the parallelisation
                more obvious to the compiler: rather than relying on the compiler's
                optimiser to spot the parallelisation opportunities. This only occurs

      The performance test suite generates a report for your particular compiler
      showing which method is likely to work best, the following tables show the
      results for MSVC-14.0 and GCC-5.1.0 (Linux). There's not much to choose between
      the various methods, but generally loop-unrolled methods perform better. Interestingly,
      ordering the code to try and "second guess" possible optimizations
      seems not to be such a good idea (method 3 below).
