- // DESCRIPTION:
- // ~~~~~~~~~~~~
- //
- // This file tests the zeta function. There are two sets of tests:
- // 1) Sanity checks: comparison to test values created with the
- // online calculator at functions.wolfram.com
- // 2) 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.
- //
- void expected_results()
- {
- //
- // Define the max and mean errors expected for
- // various compilers and platforms.
