To put things another way: how many people do you expect to thinking in terms of persentage differences between floating point numbers? I'm afraid we (mostly) all think in terms of epsilon units, and once in that mind set, converting to persentages just doesn't come naturally.
Right. At least, that's true of people like me who do mathematical stuff. Maybe there are vast herds of C++ programmers out there who think in terms of percentage tolerance, though. I'm not saying it was necessarily a bad design problem. It's a (mildly) bad design for what _I_ want, but then, I'm wrapping the whole unit test library up in my own interface anyway. :-)
What particularly you are missing/don't like in current interface presented by Boost.Test (other than FP comparison tools interface)? Gennadiy
