Sorry I have been away on holiday and couldn't comment sooner. This whole problem is rather complicated and I accept Guillaume's view that the interval library IO may best be left minimal or non-existent (though some examples may save users, especially novice users, some time in devising something to suit themselves. Terje's is a useful example, like Guillaume's - which should be documented as an example, not removed).
I have devised an uncertain scheme based on code by Evan Manning ([EMAIL PROTECTED]) Evan Marshal Manning C/C++ Users Journal, March 1996 page 29 to 38. original downloaded from ftp://beowulf.jpl.nasa.gov/pub/manning A fuller collection of even fancier classes also given in UReal.h. Standard deviation & its uncertainty added Paul A Bristow 31 Mar 98 to Jun 03. but found it rather messy to implement (especially input). It might be cleaner inheriting from the interval library (though I am not sure). Quite how to bring this, and the quantity library together, is a major task, but I remain convinced it is an important objective. Now that the major compiler incompatibility and in completeness problems appear to be solved, I will look at my code again.
