I guess the most recent builds of Valhalla are those resulting from
building from the source code in the git repo. Or are you recommending
the official ea releases instead?
I ask because I plan to use the latest release from the git repo and
keeping it current, not the ea release.

As far as I can tell, scientific computation will make use of binary
floating point numbers for a long time. Decimal floating point numbers
are still limited to biz and fin applications.
Does Intel's lib operates on decimal formats as well?
