To: J3 J3/22-147 From: Robert Corbett Subject: IEEE 754 liaison report Date: 2022-March-09 This paper is informational. It is not for vote. James Demmel and Jason Riedy published an article titled "A New IEEE 754 Standard for Floating-Point Arithmetic in an Ever-Changing World" in SIAM News last summer. Fortran and C were mentioned in the article for having adopted the new versions of the max and min operations. The subgroup on floating-point formats for AI continues its work. In addition to the four 16-bit formats they had before, they are now considering shorter formats. A new study group has been formed to work on correctly rounded implementations of the elementary functions using the new features of the new edition of IEEE 754. The C standards committee is working on integration of C with the new edition of IEEE 754. The new edition of C standard is tentatively named C23.
