Precision of root in Solve App

[John Colvin]

I have noticed that the value of a root in Numerical view or the sovle app is carrried out to only five places even though the Info box shows a full 12 place result. This is a problem if I want to copy and paste the root value with full precision to the stack.
The Vars key menus don't appear to hold the root value as a variable in the Solve app. Is there a reason why the solution is rounded to 5 places in the Solve app or is there some setting that can expand the number of decimal places to 12?
