When either an input or result is NaN, this standard does not interpret the sign of a NaN. Note, however,
that operations on bit strings — copy, negate, abs, copySign — specify the sign bit of a NaN result,
sometimes based upon the sign bit of a NaN operand. The logical predicate totalOrder is also affected by
the sign bit of a NaN operand. For all other operations, this standard does not specify the sign bit of a NaN
result, even when there is only one input NaN, or when the NaN is produced from an invalid operation.
