LOL!  Those manuals are a trip.  It seems that processor design is
a task for superhumans.

But I imagine that there are lots of people involved in the effort.

Everyone says that double (64-bits) is enough for anything.

My attitude, which is not entirely scientific, is that if you got
it then use it.  The more the better.

A lot of numerical format decisions were made at a time when the
hardware was limited by technology.  But it seems that those limits
are being removed and extreme precision (both FP and integer) is
more and more becoming possible.

But it is probably just an extravagance.  Better algorithms for
computing are more important. 

Extended precision, via software, is used a lot in cryptography.
