Specifies three presentations of numerical values, represented in character strings in machine readable form, and recognizable by humans. Provides guidance for developers of programming language standards, and implementors of programming products.

This International Standard specifies three presentations of numerical values, which are represented in character strings in a form readable by machine, for use in interchange between data processing systems. This International Standard also provides guidance for developers of programming language standards and implementors of programming products. These representations are recognizable by humans, and thus may be useful in communication between humans.

The base of representation is 10.

This International Standard applies only to numerical values consisting of a finite number of digits with or without the decimal mark. It 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.
