Display more decimals when using automatic precision

[Former user]

I like to use Settings -> Result Format -> Precision -> Automatic. But when my result contains more than 20 decimals, the result is rounded. Ex: If i calculate: 1-0.000000000000000000001 the result i get is: 1

I would like it to be: 0.999999999999999999999

I think the Automatic setting should show up to 50 decimal places; or be configurable.
