Precision and exponents in quiz

I see that we can now use exponential notation like 6.3e12 in numerical quiz answers, and that's a really good thing.  

I am not at all clear about the precision setting.  The release notes and user guide wasn't much help, and some examples would be useful.  It looks like I will need to set a precision of something like 12 if my numerical answers are small, as in the e-11 range.  Or at least that's what seemed to be working today.  If that works, great.

My real question is about setting margins or ranges.  I usually need a +/-2% to +/-5% range for calculated physics answers to accommodate internal rounding.  I don't see that I can set a range for those small numbers when I have Precision turned on.  So my correct answer might be 6.4e-12 +/-5% or +/- 3.2e-13.  This is really important.  Am I missing something?
