Can you elaborate on that. Suppose I have two threads, one in which I need
a precision of 3 and the other in which I need a precision of 7. In what
circumstances is it needed to use threads-locals to accomplish this and
how do I accomplish this?

If I want my decimal code be usable with threads, how should I write it?
