ISO/IEC 60559:2020

ISO/IEC 60559:2020 is a standard published by the International Electrotechnical Commission (IEC). Its full title is "Floating-point arithmetic". This standard covers: ISO/IEC 60559:2020(E) specifies formats and methods for floating-point arithmetic in computer systems - standard and extended functions with single, double, extended, and extendable precision - and recommends formats for data interchange. Exception conditions are defined and standard handling of these conditions is specified. It provides a method for computation with floating-point numbers that will yield the same result whether the processing is done in hardware, software, or a combination of the two. The results of the computation will be identical, independent of implementation, given the same input data. Errors, and error conditions, in the mathematical processing will be reported in a consistent manner regardless of implementation. This second edition, published as ISO/IEC 60559, replaces the first edition ISO/IEC/IEEE 60559:2011.
