If not certain result is good, you must also be ready to accept [-inf, inf] as a result of 2 + 2 operation.

As it is almost as exact as [-inf, inf] == [-inf, -1] U [1, inf]

In both cases we have some inclusion. The not important difference is [-inf, inf] is not 'smallest' for 2 + 2 result. But we all know that... that what? ... hmmmm, probably, that we all have some shortages. So let's forgive it as well as we are forgiving boost interval for its obvious misconceptions?

To be in interval and to be same interval is complete different things.

My arguments are obvious, that is not my fault you are not going to lessen. That is strange.
