OK, so in that case (at risk of appearing like the village idiot asking why it gets dark in the evenings), why is |DUT1|>1s an issue? If there are widely used dissemination formats that rely on it being <1, then it's a problem to make it larger: existing equipment won't understand and may be broken. But if all consumers are taking a higher-precison value from a website, unless they have coded if (abs (dut1) > 1) { panic ("bad dut1") }, which is possible but seems needlessly paranoid, why do they care?
