#4149: [with patch, needs review] make every field a fraction field
------------------------+---------------------------------------------------
Reporter: jhpalmieri | Owner: tbd
Type: defect | Status: new
Priority: minor | Milestone: sage-3.1.3
Component: algebra | Keywords: fraction field, fractionfield
------------------------+---------------------------------------------------
Currently in Sage:
{{{
sage: is_FractionField(FractionField(ZZ))
False
sage: is_FractionField(QQ)
False
}}}
These bother me. Since every field is its own fraction field, this patch
makes {{{is_FractionField}}} return True when the argument is a field.
I've tried to test this for incompatibilities with other parts of Sage --
I searched for {{{is_FractionField}}}, and this led to the change to
jack.py. (This change is why mhansen is cc'ed on this, since he wrote
jack.py.) I also ran {{{sage -testall}}} after committing the change.
Have I missed things?
