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.

I am interested in working on this. How do I start?

comment:2 follow-up: Changed 5 years ago by rws

First, ​http://doc.sagemath.org/html/en/developer/index.html

and please use the Google group sage-devel for questions unrelated to this specific ticket.

comment:3 Changed 5 years ago by aashu12

I am interested in adding an example to fix this. How do I know in which part of the sage directory is this located? I guess it is in src/doc/

Nope, you would have to find an appropriate place. The src/doc is mostly auto-generated. 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.

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...)

comment:20 follow-up: Changed 5 years ago by dimpase

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]

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

Yea, I will replace the existing example with the example given above in #21946
