Re: [sage-devel] Re: Inverses of matrices over RR

Well, applying a naive exact linear algebra routine to inexact data, and that's what Sage is doing here, is prone to errors. sage: A=m.augment(identity_matrix(RR,2)) sage: A [-6.12323399573677e-17 -1.72508242466029 1.00 0.000] [0.579682446302195 6.1232339957367
