CCR Condition Codes:
(Note: Since there is no destination, there is no rounding and therefore the condition codes are set assum-
ing an infinite precision result)
C
- Set if result is a NaN. Set if result is negative and not zero. Cleared otherwise.
V
- Not affected.
Z
- Set if source operands are equal. Cleared otherwise.
N
- Set if result is negative. Cleared otherwise.
I
- Set if anyone of the operands is infinity. Cleared otherwise.
LR
- Always set (initialize for the next FCMP, FCMPG combination).
–
R
- Cleared if result is a NaN. Cleared if result is negative and not zero and LR was set
(i. e., first point was rejected). Not affected otherwise.
A
- Cleared if result is a NaN. Cleared if result is negative and not zero. Not affected
otherwise.
