16 // DESCRIPTION:
17 // ~~~~~~~~~~~~
18 //
19 // This file tests the incomplete beta function inverses
20 // ibeta_inva and ibetac_inva. There are three sets of tests:
21 // 1) TODO!!!! Accuracy tests use values generated with NTL::RR at
22 // 1000-bit precision and our generic versions of these functions.
23 // 2) Round trip sanity checks, use the test data for the forward
24 // functions, and verify that we can get (approximately) back
25 // where we started.
26 //
27 // Note that when this file is first run on a new platform many of
28 // these tests will fail: the default accuracy is 1 epsilon which
29 // is too tight for most platforms. In this situation you will
30 // need to cast a human eye over the error rates reported and make
31 // a judgement as to whether they are acceptable. Either way please
32 // report the results to the Boost mailing list. Acceptable rates of
33 // error are marked up below as a series of regular expressions that
34 // identify the compiler/stdlib/platform/data-type/test-data/test-function
35 // along with the maximum expected peek and RMS mean errors for that
36 // test.
