Comment (by kcrisman):
Is "content" a well-known thing (especially for non-polynomials)? I did
find the definition in the Ginac documentation, but this should probably
be slightly clarified since it will show up in the tab-completion.
Especially since this doesn't provide the corresponding `unit` and
`primpart` methods (which might even be confused with other things in
algebra) I'm reluctant for this to go in by itself. Also,
{{{
sage: (2*x+4*sin(y)).content(2*x)
2*x + 4*sin(y)
}}}
and things like that seem to not really be in the spirit of this. If
anything, shouldn't this content be `1`? Or should this be disallowed? I
don't think it can be considered user error with such minimal doc of an
unfamiliar term.
That said, I realize this is needed for #13609 and hence #13729, so I will
try to be responsive to any responses!
