Dear forum, I'm confused by the following behaviour:
> ZZ := HomalgRingOfIntegers(); > x := 2 / ZZ; 2 > x in ZZ; false I'm trying to construct a sparse matrix using Gauss, then feed that into Homalg (using GaussForHomalg), e.g. as follows: > d := SparseZeroMatrix(2, 2, ZZ); > SetEntry(d, 1, 1, 2); > complex := HomalgComplex( 2 * ZZ); > Add(complex, HomalgMatrix(d, ZZ)); This causes an error on the "SetEntry" line where it complains that 2 isn't in ZZ. (Nor are "2 / ZZ" or "2 * One(ZZ)" or various other similar combinations.) I've also tried replacing HomalgRingOfIntegers with just Integers, which makes "SetEntry" happy but then fails later on when I try to add the sparse matrix to the complex. Is there some combination of commands I can use to make both Gauss and Homalg happy?
