Should it be modified to reflect IEEE semantics? See http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2001May/0030.html 5790 1 sandygao 2005-09-07 19:43:44 +0000 A straw poll was held for the following questions: Should bit patterns be allowed to be specified for NaNs? Should there be a distinction made between signalling and quiet NaNs? Is NaN a value? Does NaN compare equal to NaN? Should NaNs be comparable to non-NaN values? Are -0 and +0 the same value? The results of the poll were summarized in the following meeting minutes: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2001Jul/0014.html No firm decisions made to date. Status 2002/01: Dave P. and Ashok Malhotra have proposed the following resolution/text: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002Jan/0066.html Further discussion: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002Jan/0101.html 5791 2 sandygao 2005-09-07 19:44:20 +0000 The WG resolved that this should be classified as an error, and the editors are to prepare final wording for an erratum that reflects the decisions made at the 02/01 telecon: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002Feb/0009.html Proposed erratum text reviewed at the March 28 telecon. The WG noted a possible contradiction in the definition of zero in the erratum for R-22 with our decision on R-97 and concluded that this erratum text is not yet ready, and instructed the editors to deal with R-22 and R-97 in the same erratum. Status 04/24: New erratum text proposed: http://lists.w3.org/Archives/Member/w3c-xml-schema-ig/2002Mar/0131.html Status 05/02: Revised text approved. Erratum E2-40 added.
