// DESCRIPTION:
// ~~~~~~~~~~~~
//
// This file tests the Carlson Elliptic Integrals.
// There are two sets of tests, spot
// tests which compare our results with the published test values,
// in Numerical Computation of Real or Complex Elliptic Integrals,
// B. C. Carlson: http://arxiv.org/abs/math.CA/9409227
// However, the bulk of 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.
//
void expected_results()
{
//
// Define the max and mean errors expected for
// various compilers and platforms.
