Simple example.
Say, we are trying to estimate some physical value with interval calculation depending on some measured values (as values are measured, they are not exact, known to us as some ranges of possible values, it's quite natural to use interval calculations here).
Let it be some mass.
A = [1,2] B = [-1, 1]
M = A / B
Calculated result with boot interval is [-infinity, -1].
It gives [-inf,+inf] for me. If you get something different, please file a bug report in https://svn.boost.org/trac/boost/ with a compilable example and as much information as you can so we can reproduce your result.
OK, but mass cannot be negative...
Correct part of answer [1, infinity] which means that we have at least estimation of minimum for calculated value is lost...
