+// DESCRIPTION:
+// ~~~~~~~~~~~~
+//
+// This file tests the functions powm1 and sqrt1pm1.
+// 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.

+ ".*", // compiler
+ ".*", // stdlib
+ ".*", // platform
+ ".*", // test type(s)
+ ".*", // test data group
+ ".*", 5, 2); // test function
+
+ //
+ // Finish off by printing out the compiler/stdlib/platform names,
+ // we do this to make it easier to mark up expected error rates.
