13 | // DESCRIPTION: | |
14 | // ~~~~~~~~~~~~ | |
15 | // | |
16 | // This file tests the zeta function. There are two sets of tests: | |
17 | // 1) Sanity checks: comparison to test values created with the | |
18 | // online calculator at functions.wolfram.com | |
19 | // 2) Accuracy tests use values generated with NTL::RR at | |
20 | // 1000-bit precision and our generic versions of these functions. | |
21 | // | |
22 | // Note that when this file is first run on a new platform many of | |
23 | // these tests will fail: the default accuracy is 1 epsilon which | |
24 | // is too tight for most platforms. In this situation you will | |
25 | // need to cast a human eye over the error rates reported and make | |
26 | // a judgement as to whether they are acceptable. Either way please | |
27 | // report the results to the Boost mailing list. Acceptable rates of | |
28 | // error are marked up below as a series of regular expressions that | |
29 | // identify the compiler/stdlib/platform/data-type/test-data/test-function | |
30 | // along with the maximum expected peek and RMS mean errors for that | |
31 | // test. | |
