Description
It turns out that not only can one declare integer, one can declare noninteger. See here. Let's add an example pointing this out, perhaps with the example from this question.

First, http://doc.sagemath.org/html/en/developer/index.html
and please use the Google group sagedevel for questions unrelated to this specific ticket.

I am interested in adding an example for this. How do I know in which part of the sage directory is this located? I guess it is in src/doc/
comment:4 Changed 4 years ago by
Nope, you would have to find an appropriate place. The src/doc is mostly autogenerated. Instead, try to add to the documentation for the command mentioned in the question mentioned in the ticket description. The solve
command is in src/sage/symbolic/relation.py or at least that is one place.

In such cases you can set positive again yourself.

Replying to dimpase:
With all respect,
In case one of the solutions while solving an equation is a real number::makes little sense, in particular in the context of this ticket. I'm requesting a clarification on #21946
Yea, I can change that statement to a more clear one. Also, #21946 and this ticket are not dependent.

this ticket is closed. Any changes to the branches here will be ignored. (So it should go to another ticket, say #21946) But still, your branch did not and does not make sense. The purpose of this ticket is to document and provide a test for noninteger
assumption. E.g.
sage: var('K') K sage: assume(K, 'noninteger') sage: solve([K^2==1],K) []
The doctring should say what this test doing: it is showing how to use this type of assumption, and not something about reals. (Yes, I agree that the link for an example in the ticket description is somewhat misleading, but, well...)

even better example:
sage: solve([K^3==1],K) [K == 1/2*I*sqrt(3)  1/2, K == 1/2*I*sqrt(3)  1/2]
