(It's fine as is.)

The previous sentence is rather hard to parse. What (other) part of
the sentence does "to provide auxiliary information" relate to.
I suggest splitting the sentence in two and rewording.

You suddenly introduce "floating-point control mode" here.
How does it relate to the preceding sentences? It's not clear.
Going off to look at the standard... I see that actually your
sentences come pretty much straight from the standard. So, first, I
think the standard could have been clearer here. Second, and more
important, (for copyright reasons) we are on shaky ground if we just
lift whole passages from the standard. The text does really need to
be in your own words. Can you come up with something?
Alternatively, I guess we could explicitly quote the standard.
Something like
