Negation (and abs and copysign) can never raise any exceptions even with signaling NaN arguments. Conversion between integers and floating-point *can* raise exceptions (depending on the types involved, e.g. conversions from int to IEEE double are always exact with no exceptions raised). And conversions from integer to floating-point, when the types mean they aren't necessarily exact, depend on the rounding mode (whereas conversions from floating-point to integer types always truncate towards 0). -- Joseph S.
