Hi Russell Hires,
We have created a sample in NumericTextBox with the format set to "n0." However, on our end, it doesn't display the decimal values as expected. For your convenience, we've prepared a video illustration and a sample for your reference.

If there's a possibility that we misunderstood your requirement, could you please provide additional details about your specifications? If feasible, sharing a video illustration would greatly assist us in better understanding your needs, enabling us to provide you with a more accurate solution
Regards,
Priyanka K
