[Cfp-interest 1309] WG14 meeting minutes for topics of interest to our C FP group

[Rajan Bhakta]

Attendees (from C FP): Rajan, Fred

Note: We didn't get to discuss the C FP function naming issue, though we 
did discuss the WANT macro issue.

Papers:

  Thomas, C2X proposal - TS 18661-4a [N 2355]
    Result: Adopt 18661 part 4a (no reduction functions) into C2X.

  Thomas, update for C2X payload functions [N 2356]
    Result: Adopt N2356 into C2X.

  Tydeman, FE_TONEARESTFROMZERO w.r.t. FLT_ROUNDS [N 2319]
    Result: N2319 to be put into C2X.

  Tydeman, Precision and NAN/NAN(...) and INF/INFINITY [N 2320]
    Result: Want something along the lines of the macro addition part of 
N2320 to be put into C2X. Requesting a new paper for better wording for 
this.

  Tydeman, Nextafter/nexttoward/nextup/nextdown [N 2321]
    The chairman for IEEE has a use case for the existing words for this 
so withdrawing this change request.

  Tydeman, SD3 9: PreProcessor unspecified line numbers [N 2322]
    Result: N2322 to be put into C2X.

  Tydeman, SD3 1: DR 440: Test macros for FP being 754 types [N 2323]
    Result: Want something like N2323 option 1 to be put into C2X.
 
  Tydeman, SD3 11: Maximum normalized FP number [N 2325]
    Result: N2325 be put into C2X.

  Tydeman, Merge DR 432+467 [N 2326]
    Result: N2326 be put into C2X with editorial changes on the footnote 
expected.

DR's:

  DR501: Making DECIMAL_DIG obsolescent
    Result: Move DR501 to C2X.

  TS 18661-* DR's:
    DR13: Move to C2X (C FP action item).
    DR16: Move to C2X (C FP action item).
    DR20-25: Move to C2X (C FP action item).
    Thomas, P4 CR for rootn case differs from IEEE 754 [N 2309]
      Result: Assigned to DR26.
      Put into TS 18661-4 and C2X (C FP action item).

New action items:
    C FP: Give 18661 part 4a (not reduction functions) for inclusion into 
C2X.
    C FP: Put N2309 into TS 18661-4 and C2X.
    TS DR13: Move to C2X (C FP action item).
    TS DR16: Move to C2X (C FP action item).
    TS DR20-25: Move to C2X (C FP action item).
