scope:

This standard is a simplied version and a subset of the IEEE Std 1788^TM-2015 for Interval Arithmetic and includes those operations and features of the latter that in the the editors' view are most commonly used in practice. IEEE Std 1788.1-2017 species interval arithmetic operations based on intervals whose endpoints are IEEE Std 754^TM-2008 binary64 oating-point numbers and a decoration system for exception- free computations and propagation of properties of the computed results.

A program built on top of an implementation of IEEE Std 1788.1-2017 should compile and run, and give identical output within round o, using an implementation of IEEE Std 1788-2015, or any superset of the former.

Purpose

Compared to IEEE Std 1788-2015, this standard aims to be minimalistic, yet to cover much of the function- ality needed for interval computations. As such, it is more accessible and will be much easier to implement, and thus will speed up production of implementations.
