  22 // DESCRIPTION:
  23 // ~~~~~~~~~~~~
  24 //
  25 // This file tests the functions log1p and expm1.  The accuracy tests
  26 // use values generated with NTL::RR at 1000-bit precision
  27 // and our generic versions of these functions.
  28 //
  29 // Note that when this file is first run on a new platform many of
  30 // these tests will fail: the default accuracy is 1 epsilon which
  31 // is too tight for most platforms.  In this situation you will
  32 // need to cast a human eye over the error rates reported and make
  33 // a judgement as to whether they are acceptable.  Either way please
  34 // report the results to the Boost mailing list.  Acceptable rates of
  35 // error are marked up below as a series of regular expressions that
  36 // identify the compiler/stdlib/platform/data-type/test-data/test-function
  37 // along with the maximum expected peek and RMS mean errors for that
  38 // test.
  39 //

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