 Test lexical_cast_loopback_test is more like an exception from the rule.
 It is used to determinate the accuracy of the upcoming algorithm. Some of
 the compilers currently do not fail the test, so this test must continue
 to pass successfully on those compilers. [[BR]]
 Other tests use BOOST_CHECK_CLOSE for floats.[[BR]]

 Some work on this ticket has been already done in [72925].
