[中文适用范围]： 提供以机器可读的字符串表示的数值的三种表示形式，用于数据处理系统之间的交换。 为开发编程语言标准和实现编程产品提供指导。 这些表示是人类可以识别的。 标准仅适用于由有限位数（带或不带小数点）组成的数值。 [外文原描述]： Provides three presentations of numerical values represented in character strings readable by machine for use in interchange between data processing systems. Gives guidance for development programming language standards and implementation programming products. These representations are recognizable by humans. Standard applies only to numerical values consisting of a finite number of digits with or without the decimal mark.
