17 // DESCRIPTION:
18 // ~~~~~~~~~~~~
19 //
20 // This file tests the functions powm1 and sqrt1pm1.
21 // The accuracy tests
22 // use values generated with NTL::RR at 1000-bit precision
23 // and our generic versions of these functions.
24 //
25 // Note that when this file is first run on a new platform many of
26 // these tests will fail: the default accuracy is 1 epsilon which
27 // is too tight for most platforms. In this situation you will
28 // need to cast a human eye over the error rates reported and make
29 // a judgement as to whether they are acceptable. Either way please
30 // report the results to the Boost mailing list. Acceptable rates of
31 // error are marked up below as a series of regular expressions that
32 // identify the compiler/stdlib/platform/data-type/test-data/test-function
33 // along with the maximum expected peek and RMS mean errors for that
34 // test.
35 //

52 // Finish off by printing out the compiler/stdlib/platform names,
53 // we do this to make it easier to mark up expected error rates.
