Title: Clarify "approximation" for real values
Submitted by: J3
Status: For Consideration
References:
Basic Functionality: State in one place that the standard recognizes that
(essentially) all real and complex values and computations
involve approximations.
Rationale: In some places we say real computations are approximate
(e.g., SQRT). In other places we do not (e.g., +).
Probably nobody will think that + must be exact, but
why not state it clearly.
It will shorten the standard.
Estimated Impact: This is editorial only.
Detailed Specification: Put the words in the standard once.
Remove all/most of the occurrences of
"processor-dependent approximation".
