[Cfp-interest 2824] Re: CFP review of TS-4 and TS-5 revisions

[Jim Thomas]

Here are suggestions for changes from my review so far. This list does not include suggestions made (by others or myself) in other CFP email messages.

- Jim Thomas


TS-4r

Page vi, Line 26: Delete “new”.
 
Page vii, Line 22: Change “C18” to “C17”.
 
Page viii, Lines 1-3: Change:
 
This document includes the specification in ISO/IEC TS 18661-4 that was not incorporated into C23, namely support for reduction functions. It also includes specification to support the augmented arithmetic operations introduced in IEC 60559:2020.
 
to:
 
This document updates ISO/IEC TS 18661-4. It retains the feature that was not incorporated into C23, namely thereduction functions. It also adds support for the augmented arithmetic operations introduced in IEC 60559:2020.
 
Page viii, Line 4: Change “will update” to “updates”.
 
Page 1, Lines 12, 18, 23: Change the three occurrences of “this technical specification” to “this document”.
 
All Synopses, e.g. Page 3, Lines 20 and 33: Add the appropriate feature guard, e.g. change:
 
#ifdef __STDC_IEC_60559_BFP__
double reduc_sum(size_t n, const double p[static n]);
…
#endif
#ifdef __STDC_IEC_60559_DFP__
_DecimalN reduc_sumdN(size_t n, const _DecimalN p[static n]);
…
#endif
 
to:
 
#ifdef __STDC_IEC_60559_FUNCS_REDUCTION__
#ifdef __STDC_IEC_60559_BFP__
double reduc_sum(size_t n, const double p[static n]);
…
#endif
#ifdef __STDC_IEC_60559_DFP__
_DecimalN reduc_sumdN(size_t n, const _DecimalN p[static n]);
…
#endif
#endif
 
 
 
TS-5

This document includes the specification in ISO/IEC TS 18661-4 that was not incorporated into C23, namely support for reduction functions. It also includes specification to support the augmented arithmetic operations introduced in IEC 60559:2020.
 
A separate document will update ISO/IEC TS 18661-5, which was not incorporated into C23.

This document updates ISO/IEC TS 18661-5, which was not incorporated into C23.
 
Page 1, Lines 11, 18, 20, 22, 24, 26: In five places, change “this technical specification” to “this document”.
 
Page 2, Line 26: Change “this technical specification” to “this document”.
 
Page 2, Line 27: Change “support the attributes recommended by” to “support attributes recommended by”.
 
Page 12, Lines 5 and 6: Change “If the implementation defines __STDC_IEC_60559_FUNCS__ and it provides a set of correctly rounded math functions” to “If the implementation provides a set of correctly rounded math functions”.
 
Page 13, Lines 1-3: Change:
 
The implementation should produce a diagnostic message if ...
 
to:
 
Recommended practice
The implementation is encouraged to issue a diagnostic message if ...
 
Page 13, Line 26: Change: 
 
1 + ⎡p×log10(2)⎤	
 
to:
 
1 + ⌈p×log10(2)⌉
 
Page 14: Lines 1-2: Change:
 
—     The code does not depend on the sign of a zero result or the quantum of a decimal result for the fmin, fmax, fminmag, and fmaxmag functions when the arguments are equal.

to:

—     The code does not depend on the quantum of a result for the decimal maximum and minimum functions in C23 7.12.12 when the arguments are equal.

Page 15, Line 18: Change “(7.12.14.4)” to “(C23 7.12.14.4)”.

The people already named in the list below chose sections at the CFP meeting today. It would help to have at least two reviewers for most of the sections. Please complete your review and send comments to cfp-interest at oakapple.net <mailto:cfp-interest at oakapple.net> by 23 August. CFP will resolve any issues at its 30 August meeting.
