| // 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.
