If
c
(
exp
) has overflowed (step 11) in the positive direction, then step 14
sets
c
(
exp
) to the most positive extended-precision format value. If
c
(
exp
)
has overflowed in the negative direction, then step 14 sets
c
(
exp
) to the
most negative extended-precision format value.
If
c
(
exp
) has underflowed (step 12), then step 15 sets
c
to 0; that is,
c
(
man
) = 0 and
c
(
exp
) = –128.
