Hi,
I've been having an issue with a program I've written in sage. I need
to calculate a polynomial mod 7. When I do this using the command
line, I don't have any trouble. Example:
sage: x = var('x')
sage: y = var('y')
sage: IntegerPolyRing.<x,y> = ZZ[]
sage: ideal = -6*x - y
sage: ideal = IntegerPolyRing(ideal)
sage: print type(ideal)
<type
'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular'>
sage: print ideal%7
x + 6*y
However, when my program calculates an ideal which is equal to -6*x -
y and has the type
'sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular',
it always gets 0 for ideal%7. This happens for every ideal that the
program calculates. I'm flummoxed. Any ideas as to what might be
causing this?
