> The latest issue (Vol. 25, No. 3, 2006) of the Journal of Computers in
> Mathematics and Science Teaching published by the Association for the
> Advancement of Computing in Education (AACE) starts with an article by
> William Richardson from Francis Marion University on the treatment of
> computational precision etc. in an introduction programming course for
> scientists and engineers.
> 
> The article starts with a known problem - that round off errors
> sometimes make results of numerical computations unreliable - and cites
> interval arithmetic as the most natural solution to this problem (with a
> reference to Hayes' 2003 popular article in American Scientist).
> Following Hayes, Richardson cites the lack of hardware support and the
> lack of standardized treatment of intervals in programming langauges
> among the main reasons why interval computations are not as widely used
> as they could be.
> 
> He also mentions the need for operations with large integers and large
> reals. 
> 
> It is very good that intervals are mentioned in an article aimed at
> those who teach math and science, additional exposure is never a bad
> idea. 
> 
> Anecdotal evidence shows that (while there is only 1-2 pages about
> intervals, still) thos article is a good exposure: I learned about this
> article from my wife Olga who is now teaching future math teachers at
> our College of Education and who is subscibed to this joirnal as part of
> her membership in AACE; the article is first in this issue.
> 
> Maybe someone from our field can submit, to this (or similar
> education-orineted) journal an education-oriented article specifically
> devoted to intervals?
