// DESCRIPTION:
|
||
|
|
// ~~~~~~~~~~~~
|
||
|
|
//
|
||
|
|
// This file tests the functions log1p and expm1. The 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.
