Category: Request for information/clarification Committee Draft subsection: various Title: What is the precision of floating point calculations ? Detailed description: DR 063 asked, for C89, what was the required precision of the results of the various floating point operators and functions. To date this has not been answered. I am not aware enough of the issues to be able to write a good answer myself, but references to IEC 559 and annex F are not a sufficient solution.
