Re: Please listen to Ulrich here...



Ian,

As far as I can tell the only time when a case can be made that EDP is essential for interval computations is when all interval inputs are degenerate and therefore infinitely precise. Otherwise, with interval bounds on the accuracy of typical measured data, I don't see the requirement for EDP. I continue to wait to see even one practical example thereof.

Cheers,

Bill

Ian,

I attach a few more pages which might be interesting for you.

Best regards

P.S.: These details are more or less known since 1980. But obviously they are not wide spread. I discussed this matter already with IEEE754R. At the end they said they don't have the necessary knowledge to make a clear decision. A few month after the first edition of my book was published in 2008 IEEE 1788 was founded. Now it seems that we end with the same situation.

Repeatedly pointing out the hardware aspects makes me wonder if the argument for EDP being essential for interval computation other than EDP of intervals is simply
unsupported.
