Notes:
1. The sign of the result is the exclusive-OR of the signs of the source operands.
2. If the absolute value of the result is less then 2
–126
, the result is zero with the sign being the exclusive-OR of the signs of the
source operands. If the absolute value of the product is greater than or equal to 2
128
, the result is the largest normal number
with the sign being exclusive-OR of the signs of the source operands.
