I have re-read everything I can find about BOOST_CHECK_CLOSE, and the doc on floating point comparison algorithms (i.e.close_at_tolerance).

BOOST_CHECK_CLOSE( x, y, t ) checks that x and y does not differ for more then t persent. IOW: |x-y|/|x| < t and |x-y|/|y| < t

Currently, I have a test, using BOOST_CHECK_CLOSE() which passes, no matter how big/small I set the tolerance; yet the values are different.

Could you show your tests and Boost.Test output. Gennadiy
