In case others also saw gibberish in the "last sentence of 5.2"
posted by Mike Cowlishaw, here it is in plain characters:
If x is infinite, Q(x) is +Infinity.
This of course makes the exponent of Finite/Infinity "as small as
possible", i.e. that rarely seen DFP zero that actually looks like
zero (if the sign bit is zero too).
(Confirmed by executing a DDTR instruction on an IBM Z10.)
