Personally I would prefer a fraction to a percentage.
New names for this MACRO(s)?
BOOST_CHECK_CLOSE_RELATIVE(real1, real2, fraction) (real1 - real2) / real1 <
BOOST_CHECK_CLOSE_ABSOLUTE(real1, real2, difference) (real1 - real2) <

| Subject: [boost] BOOST_CHECK_CLOSE plans
| I have several outstanding issues with BOOST_CHECK_CLOSE. Users keeps
| confuse it with absolute comparison and error message is misleading.
| What I plan is to switch to percentage based specification of the
| tolerance. IOW BOOST_CHECK_CLOSE( a, b, p ) will check that (a-b)/a does not
| exceed p percent. Error message I will change accordingly.
| The only problem is that will not be backward compatible. Does anybody see
| a solution to overcome this?
