 Description modified (diff)
 Milestone changed from sage6.4 to sage6.7
 Report Upstream changed from N/A to Reported upstream. Developers acknowledge bug.
Also, from comment 16 of #12967:
sage: cmp(SR(oo), sqrt(2)) RuntimeError: comparing typeid's
comment:3 Changed 4 years ago by
 Dependencies set to pynac0.3.7
 Report Upstream changed from Reported upstream. Developers acknowledge bug. to Fixed upstream, in a later stable release.
With the latest commit in Pynac we now have:
sage: ex = sin(x).series(x==0, 3) * x sage: str(ex) 'x*(1*x + Order(x^3))' sage: cmp(SR(oo), sqrt(2)) 1 sage: bool(SR(oo) < sqrt(2)) False sage: bool(SR(oo) > sqrt(2)) False
This means there is no longer a runtime error, there is however still code missing in Pynac and Sage to correctly handle these requests (see #12967 and the discussion in #18393).

 Milestone changed from sage6.7 to sage6.8
 Summary changed from Pynac RuntimeError: comparing typeid's to doctest fixed Pynac RuntimeErrors
The last of the cases given in the comments is now fixed in #18877, so this ticket should doctest all related ones.

comment:7 Changed 4 years ago by
Wrong, the cmp
problem still remains...
sage: cmp(SR(oo), sqrt(2)) 1 sage: cmp(SR(oo), sqrt(2)) 1 sage: cmp(sqrt(2), SR(oo)) 1 sage: cmp(sqrt(2), SR(oo)) 1
but this is clearly #16397 so this ticket should doctest the bool
fixes.

Please remove all those bool
s. You can just write assert(x > y)
or assert(not x > y)
.

I get the same(?) error in the current #7660.
