Description:
The absolute values of the pair of single precision values in the significand field of FR
f
3
are computed, negated and stored in the significand field of FR
f
1
. The exponent field of
FR
f
1
is set to the biased exponent for 2.0
63
(0x1003E) and the sign field of FR
f
1
is set
to positive (0).
If FR
f
3
is a NaTVal, FR
f
1
is set to NaTVal instead of the computed result.
Operation: See “fpmerge — Floating-point Parallel Merge” on page 3:111.
