What is the expected behavior for > sNaN. If you tweak the testcase slightly as follows: All the comparison operations raise exceptions for sNaN. See IEEE 754. "Invalid operation is the only exception that a comparison predicate can signal. All predicates signal the invalid operation exception on signaling NaN operands. The predicates named Quiet shall not signal any exception, unless an operand is a signaling NaN. The predicates named Signaling shall signal the invalid operation exception on quiet NaN operands.".
