My favorite bug from when I was an undergrad... sage: B = matrix([[ -3, 2, 1 ], ....: [ 2,-4, 4 ], ....: [ 1, 2,-5 ]]) sage: B.rank() 2 sage: (0.5*B).rank() 3 sage: (2 * 0.5*B).rank() 3 sage: (2 * 0.5*B) == B True -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
