assume(x>0); additionally(x,integer); Beta 2 release
I was doing the assumptions above, and it says when I type about(x)...
[[0 infinity] 0]

Is this saying that it is including x? x>0 should be saying 1 or greater, not equal to 0.
I tried additionally(x != 0) (I used the not equal symbol) and it wouldn't accept it as an argument.

ideas?
Thx

Try it the other way round, first assume(x,integer), then additionally(x>0). Now about(x) provides: [DOM_INT [[0 infinty]] [0]].

But isn't that still allowing x to be equal to zero?
That seems to be x>=0, not x>0....

[DOM_INT [[0 infinty]] [0]]
(2) [[0 infinty]] --> Hypothesis interval matrix
(3) [0] --> List of interval exclusions

0 is being excluded, does not participate.

I see, so is this described in any documentation? I mean about the Hypothesis interval matrix and list of interval exclusions? i.e. How did you know this? :-)
