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?
