#1245: Error coercing multivariate polynomial rings with one variable into
composite integer rings
---------------------------------------------------------------+------------
Reporter: ncalexan | Owner:
malb
Type: defect | Status:
closed
Priority: critical | Milestone:
sage-3.1.4
Component: commutative algebra | Resolution:
fixed
Keywords: coercion coerce multivariate univariate composite |
---------------------------------------------------------------+------------
Changes (by mhansen):
* status: new => closed
* resolution: => fixed
* milestone: sage-3.2.1 => sage-3.1.4
Comment:
This has been fixed in at least Sage 3.1.4
{{{
sage: sage: PolynomialRing(ZZ, 1, 'x').gen() * Mod(1, 3)
x
sage: sage: PolynomialRing(ZZ, 1, 'x').gen() * Mod(1, 9)
x
sage: _.parent()
Univariate Polynomial Ring in x over Ring of integers modulo 9
