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 Donald

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....
