A few registers have now become NAN due to a divide by zero. I have taken care of that condition but the NAN has returned to some of the registers by some other means. Is there an instruction that can test if a particular register has become NAN? I want to implement logic that can do that test automatically and then apply logic to fix it or work around it. I am aware of %SW17. I am using Unity Pro.
