Emulating round-to-nearest-ties-to-zero "augmented" floating-point operations using round-to-nearest-ties-to-even arithmetic
Résumé
The IEEE 754 Standards Committee for Floating-Point Arithmetic is recommending, in its draft standard, that new "augmente"' operations should be added in the next release of the standard. These operations use a new "rounding direction": round to nearest ties-to-zero. We show how they can be implemented using the currently available operations, using rounded-to-nearest ties-to-even.
