[sage-support] Bug in product of polyhedra

The cartesian product of two polyhedra doesn't work if their dimensions are different: Consider the following (just run on sagenb.org): sage: B1 = Polyhedron(vertice=[(0,),(1,)]) sage: B1 A 1-dimensional polyhedron in ZZ^1 defined as the convex hull of 2 vertices sage: B2 = B1*B1 sage: B1

Re: [sage-support] ellsearch on sagenb.org

If you really want, you can access PARI's ellsearch through Sage using something like pari('''ellsearch("11a1")''') But, as others have said, Sage itself also contains the elliptic curve database, so why bother? -- You received this message because you are subscribed to the Google Groups "s

[sage-support] Integer division of rationals

Helloo everybody ! This is what I spent the last hour finding : sage: x = 1/2 sage: x 1/2 sage: x//2 1/4 I got some variable x as input, which was of rational type when I expected it to be integer type (does not matter, this rational was equal to an integer in my case). Unfortunately, x//2 (

[sage-support] Unwanted factorization...

Hello, the following code prints *21**(x^2 + 2*x)/(28*x^2 - 3*x - 40) but I would simply like to have (21*x^2 + 42*x)/(28*x^2 - 3*x - 40) Can I acheive this ? Best regards. C. === CODE === param = [] for i in range(8): param.append(randint(-10,10)) num(x) = (param[0]*x - para
