I would not say that I'm "familiar" with it, but I have heard
noises about it.


is a good resource.


Is another one.

They intend to standardize new floating point formats including
3 sizes of decimal and new 128-bit binary floats, be more
specific about exceptions and handlers for those exceptions,
combine it with IEEE 874 (radix-independent floating point
handling) and otherwise *reduce* the number of choices open
to implementers.  There are various other goals but I think
those are the major ones.

Oh, one other thing in here that I applaud; they're standardizing a
hardware operation they call "fused multiply-add" which is key to
bigfloat support, and including an annex on working with arbitrary-
sized float formats.
