  // DESCRIPTION:
  // ~~~~~~~~~~~~
  //
  // This file tests the functions log1p and expm1.  The accuracy tests
  // use values generated with NTL::RR at 1000-bit precision
  // and our generic versions of these functions.
  //
  // Note that when this file is first run on a new platform many of
  // these tests will fail: the default accuracy is 1 epsilon which
  // is too tight for most platforms.  In this situation you will
  // need to cast a human eye over the error rates reported and make
  // a judgement as to whether they are acceptable.  Either way please
  // report the results to the Boost mailing list.  Acceptable rates of
  // error are marked up below as a series of regular expressions that
  // identify the compiler/stdlib/platform/data-type/test-data/test-function
  // along with the maximum expected peek and RMS mean errors for that
  // test.
  //

     //
     // Define the max and mean errors expected for
     // various compilers and platforms.
