07-271R1 To: J3 From: Dick Hendrickson Subject: Interpretation: Field width for INFINITY output Date: 2007 August 02 NUMBER: F03/0100 TITLE: Error in field width for special cases of signed INFINITY output KEYWORDS: formatted output, signed infinity DEFECT TYPE: Erratum STATUS: J3 consideration in progress QUESTION: Is there an error in the description for the output of a IEEE infinity with a sign and a field width of 3 or 8? 228:36-37 describes the output for an IEEE infinity and special cases field widths of 3 and 8. But, the special casing doesn't consider the possibility of a plus or minus sign in the field. A signed infinity should be special cased for field widths of 9 and 4. ANSWER: Yes, there is an error in the special cases. Edits are provided to correctly describe the required field widths for signed infinities. EDITS: [228:7] In the paragraph beginning "For an internal value that is an IEEE infinity." in 10.6.1.2.1 change "If is less than 3" to "If no sign is produced and is less than 3". Add after that sentence: "If a sign is produced and is less than 4, the field is filled with asterisks; otherwise, if is less than 9, the sign followed by 'Inf' is produced.
