Re: Accuracy of cancellative addition and subtraction
Marco
It seems you are right, thanks for pointing out this omission. Will you suggest the needed change to the wording of 12.10.2, please?
I disagree about your "obviously", below. See the examples in 12.12.5. It may be quite easy but it is also easy to get it wrong. If you have an algorithm that makes it simple, ensure that this is posted on the "tips for implementers" part of the 1788 web site.
