const (
	// NormalNaN is a quiet NaN. This is also math.NaN().
	NormalNaN uint64 = 0x7ff8000000000001

	// StaleNaN is a signaling NaN, due to the MSB of the mantissa being 0.
	// This value is chosen with many leading 0s, so we have scope to store more
	// complicated values in the future. It is 2 rather than 1 to make
	// it easier to distinguish from the NormalNaN by a human when debugging.
	StaleNaN uint64 = 0x7ff0000000000002
