Description Michael Kay 2011-06-21 15:42:55 UTC 
The Functions and Operators specification refers to both the 1985 and 2008 editions of IEEE 754. The references should probably all change to refer to the 2008 edition.
Comment 1 Jim Melton 2011-06-21 21:16:15 UTC 
Why, Mike?  We're not adopting precisionDecimal.  What other changes 
are  in IEEE 754:2008 that we need to recognize?


Just curious,
    Jim
Comment 2 Michael Kay 2011-06-21 21:48:06 UTC 
The trigonometric functions are defined in terms of 754:2008. I've no 
idea whether 754:1985 defines these, or whether the definitions are the 
same. Having invested in a copy of the 754:2008 spec, I've no particular 
enthusiasm for buying a copy of 754:1985 just to find out whether it has 
changed.

I think we can be reasonably confident that there won't be any material 
changes to the definitions of double arithmetic, other than bug fixes, 
between the two: the spec is embodied in a lot of hardware.

Mike
Comment 3 Michael Kay 2011-06-28 16:11:29 UTC 
Agreed to update references to the latest version.
Comment 4 Michael Kay 2011-07-21 21:24:14 UTC 
All references have been updated to refer to the 2008 edition.
