ISO/IEC/IEEE 60559:2011

Information technology — Microprocessor Systems — Floating-Point arithmetic

Publication date:   Jul 7, 2011

Scope

ISO/IEC/IEEE 60559:2011(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 first
edition, published as ISO/IEC/IEEE 60559, replaces the second edition of IEC
60559.
