[boost] Re: [test] Confusion about BOOST_CHECK_CLOSE

If I want to check that two values differ by not more than just one binary ULP (least significant bit), is the BOOST_CHECK_CLOSE tolerance

numeric_limits<double>::epsilon() * 100.?

*100. because tolerance is in percent - sniff ;-)

Documentation explicitly emphasize that tolerance is in percents. Previously there was a lot of confusion, when people tried to employ this check to do absolute comparisons. Now it's clear - comparisons are relative (to the value modules) Gennadiy
