Operation

Selects the greater numeric source or destination value using IEEE NaN and zero rules.

Selects the greater numeric operand; one NaN selects the numeric operand, two NaNs use the common NaN-selection rule, and a positive-zero/negative-zero pair selects positive zero. A signaling NaN generates NV.
