Standard extended format for binary floating-point numbers?

[Gideon Yuval]

The 8087/80287/80387/80486DX/Pentium have an 80-bit format in the 
register file (called "long double" in MS C).

| Can anyone tell me if there is a standard, or an emerging standard, or a
| de facto standard, for floating point representations longer than 64
| bits?  I'd appreciate knowing what it is, and what standards body (if
| any) is working on it.
|
| Thanks.
