#2665: error in coercion between CIF and SR
----------------------------------------------------+-----------------------
Reporter: ncalexan | Owner: robertwb
Type: defect | Status: new
Priority: minor | Milestone: sage-3.4.1
Component: coercion | Resolution:
Keywords: symbolic SR complex interval field CIF |
----------------------------------------------------+-----------------------
Comment (by roed):
I would say that this is still wrong. In particular, the result
{{{
sage: CIF.has_coerce_map_from(SR)
True
}}}
is incorrect. But fixing that needs to wait on more general coercion
rewrites.
