IEEE 754-1985 governs binary floating-point arithmetic. It specifies number formats, basic operations, conversions, and exceptional conditions. The related standard IEEE 854-1987 generalizes 754 to cover decimal arithmetic as well as binary.
Note that materials provided on this page and sub-pages are not approved as IEEE standards. The two current, approved standards are 754-1985 and 854-1987. The materials provided through this page are purely informative.

The standard is undergoing revision. Participation is open to people with a solid knowledge of floating-point arithmetic. We hold monthly meetings in the San Francisco Bay area. The mailing list tracks running discussions.
Some answers to frequently asked questions are available. A large amount of material, online and dead-tree, has accumulated over the years. The earlier publications provide rationale for the current standard, IEEE 754-1985.
