(1) All denormalized inputs shall be treated as plus zero. Any underflow result shall produce plus zero.
(2) If the Destination is word or double-word and an overflow occurs(except source is NAN or INF):
If the result is positive, Destination is 32767 for Word and 2147483647 for Double Word. If the result is negative, Destination is -32768 for Word and -2147483648 for
Double Word.
(3) If the Destination is floating point, all overflows (Source is NAN or infinity) shall produce NAN (0x7FFFFFFF).
(4) If Destination is an integer and the Source is NAN or infinity, a saturated result (32767 for Word and 2147483647 for Double Word) shall be stored.
