@oblomov@sociale.network I wanted to show a case where comparing to zero is the correct thing to do. 3. That's news to me. Do you have any references to support this claim? Sure, of your matrix is sparse/symmetric/tridiagonal/whatever, you can do much better, but for a general system my impression was that there are basically just GJ and QR. QR is more precise but slower. Again, note that absolutely maximum precision wasn't the goal.

@oblomov@sociale.network 4. I don't agree. I've shown enough examples where epsilons are not needed in the first place, and a few examples where they are okay. I didn't pick them just to sort my claim - my overall programming experience confirms that epsilons are almost always the bad option. I don't see how the user input example invalidates that.
