This Japanese Industrial Standard specifies three presentations of numerical values, which are represented in character strings in a form reasonable by machine, for use in interchange between data processing systems. This Japanese Industrial Standard applies only to numerical values consisting of a finite of a finite number of digits with or without the decimal mark. This standard does not specify the mechanism to communicate the accuracy of the number being represented or the method of delimiting the numerical representations or the organization of the numerical representations into larger aggregates. This standard also provides guidance for developers of programming language standards and implementors of programming products. These representations are recognizable by humans, and thus may useful in communication between humans.
