Oops, thanks for catching the mistake S. * dmo...@deductivepress.ca [2021-01-17 12:01:41]: I agree that this needs to be fixed. Offhand, I don't know what the answer should be (for example, (1/(x*y), 0) also seems reasonable), but (0,1) is certainly not correct. So please do open a ticket. Pl

[sage-devel] quo_rem for multivariate Laurent polynomial rings

2021-01-17 Thread VulK
Dear all, can someone please confirm that the current behaviour of sage is not the expected one before I open a ticket about it? sage: R. = LaurentPolynomialRing(QQ) sage: q,r = (1/x).quo_rem(y) ; q,r (0, 1) sage: q*y + r == x False The correct
