Just found out that when IEEE 1076-2008 came out, so did IEEE 756-2008
(the floating point standard). So, now the floating point packages are
out of date with the standard.

Some of the "what to do here" has me at a loss. In the new standard,
there are 16, 32, 64, and 128 bit binary floating point definitions (the
old one had only 32 and 64, IEEE 854 had 128). Now there are base 10
exponent definitions (who would use these!) with what is called a
"density packed decimal" format. Rounding modes now have a new
"rounding direction". Lots of new functions.

Here's a draft of the new standard:

I would guess this is close to the final.
