result. The actual 96-bit result is stored in memory using the A10 and B10 operands
(instead of A and B) because shifting and limiting is not desired.
Condition Codes:
S — Computed according to the definition in A.5 CONDITION CODE COMPUTATION
L — Set if limiting (parallel move) or overflow has occurred in result
E — Set if the signed integer portion of A or B result is in use
U — Set if A or B result is unnormalized
N — Set if bit 55 of A or B result is set
Z— Set if A or B result equals zero
V — Set if overflow has occurred in A or B result
C — Set if a carry (or borrow) occurs from bit 55 of A or B result.
Note:
Refer to Section A.5 for complete details.
