The Working Group prepares a draft of the proposed standard. Generally, the draft follows the IEEE Standards Style Manual that sets guidelines for the clauses and format of the standards document. Such numbers are called denormal. The RevCom then makes a recommendation about whether to approve the submitted draft of the standard document.
A sponsoring organization is in charge of coordinating and supervising the standard development from inception to completion. On September 1,the original website was decommissioned and remains, without further updates, to redirect visitors.
NaN[ edit ] Some operations of floating-point arithmetic are invalid, such as taking the square root of a negative number. Denormalized numbers[ edit ] The number representations described above are called normalized, meaning that the implicit leading binary digit is a 1.
This program grants public access to view and download current individual standards at zero charges. Representation of non-numbers[ edit ] The biased-exponent field is filled with all 1 bits to indicate either infinity Iee standards an invalid result of a computation.
An IEEE-approved organization must sponsor a standard. Once a draft of the standard is finalized in the Working Group, the draft is submitted for Balloting approval. After the PAR is approved, a working group of individuals affected by, or interested in, the standard is organized to develop the standard.
Standards[ edit ] The standardization process[ edit ] Each year, the IEEE-SA conducts over standards ballots, a process by which proposed standards are voted upon for technical reliability and soundness.
The Antitrust Division stated its support for the patent policy revisions in a business review letter that it issued in Januaryupon request from the IEEE-SA.
It takes a majority vote of the Standards Board to gain final approval of the standard. In some cases external members are invited to vote.
Assembling a Working Group: Range and precision[ edit ] Relative precision of single binary32 and double precision binary64 numbers, compared with decimal representations using a fixed number of significant digits.
The act of reaching an invalid result is called a floating-point exception. Precision is defined as the minimum difference between two successive mantissa representations; thus it is a function only in the mantissa; while the gap is defined as the difference between two successive numbers.
In the letter, the Antitrust Division said that the provisions would unambiguously produce net benefits for consumers with insignificant anticompetitive implications. If the standard is not approved, the process returns to the drafting of the standard step in order to modify the standard document to gain approval of the balloting group.
InIEEE had over active standards, with over standards under development. The professional societies within IEEE serve as the natural sponsor for many standards. The IEEE Standards Department sends an invitation-to-ballot to any individual who has expressed an interest in the subject matter of the standard.
In general, if the RevCom recommends approval, the Standards Board will vote to approve the standard. An exceptional result is represented by a special code called a NaN, for " Not a Number ".
The IEEE standards development process can be broken down into seven basic steps: Anyone who responds positively to the invitation-to-ballot becomes a member of the balloting group, as long as the individual is an IEEE Standards Association member or has paid a balloting fee.As the world's leading standards developer, IEEE is also a leading source of information and resources on standards, their applications, and their impact on designing new products, processes, and services.
ieee标准协会是世界领先的标准制定机构，其标准制定内容涵盖信息技术、通信、电力和能源等多个领域。. IEEE offers Registration Authority programs or registries which maintain lists of unique identifiers under standards and issue unique identifiers to those wishing to register them. The IEEE Registration Authority assigns unambiguous names to objects in a way which makes the assignment available to interested parties.
The Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) is an organization within IEEE that develops global standards in a broad range of industries, including: power and energy, biomedical and health care, information technology and robotics, telecommunication and home automation, transportation, nanotechnology, information assurance, and many more.
