For an engineer, it doesn't matter so much that the determinant is exactly 0 or some 1e-12. Moreover, engineers usually deal with real, floating point numbers, rarely with pure integers.

I've always wondered if the algorithm as I described above could deliver a wrongly rounded result, in which case I would have to agree with you.
Otherwise, all it does is delivering a more accurate result, and I have no problem whatsoever with that. For those who do, just set Flag -54.
