The false positive is still there, obviously.

I think you might be referring to [set difference](http://mathworld.wolfram.com/SetDifference.html), also known as [relative complement](https://en.wikipedia.org/wiki/Complement_(set_theory)#Relative_complement). In that case, we must not forget that we are dealing with intervals over the (extended)...

You are perfectly right. I should be able to add a `x.closed_complement()` method returning the closure of the complement of `x`, which, as you said, it would be equal to...

Alternatively, since the set-theoretic complement of an instance of the Interval class is not representable with an instance of the Interval class, I could define a method that simply returns...

Thanks for the link. My library is pretty much focused on numerical computations with correct rounding, hence the restriction to floats. There is plenty of space for other libraries that...

This means that [crlibm](https://pypi.python.org/pypi/crlibm/1.0.3) did not install properly. There are two possible ways forward: 1. If you don't need any of the transcendental functions (cos, sin, exp, log etc.) that...

Can you try and tell me whether the following works? ``` >>> from interval import interval >>> x = interval[1, 2]; x interval([1.0, 2.0]) >>> x[0].sup 2.0 >>> x[0].inf 1.0...

So I believe I can close this, right?

A method to return the measure of an interval would be actually quite useful and easy to implement, and I cannot remember at the moment why I did not add...

I'll try to add it for release 1.3, but getting it right is trickier than it might seem at first.
