本标准是IEEE Std 1788TM-2015区间算术标准的简化版本和子集，包括编辑认为在实践中最常用的操作和特征。IEEE Std 1788.1-2017规定了基于区间的区间算术运算，其端点为IEEE Std 754TM-2008二进制64浮点数，以及用于无异常计算和计算结果属性传播的装饰系统。 建立在IEEE Std 1788.1-2017实现之上的程序应编译并运行，并使用IEEE Std 1788实现在四舍五入内给出相同的输出- 2015年，或前者的任何超集。

This standard is a simplified version and a subset of the IEEE Std 1788TM-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 specifies interval arithmetic operations based on intervals whose endpoints are IEEE Std 754TM-2008 binary64 floating 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 off, using an implementation of IEEE Std 1788-2015, or any superset of the former.
