I'm looking more carefully at Boost Multiprecision than I have in the 
past and have a couple of questions:

It's not clear to me how errors are handled.  For example, what happens 
in a divide by zero?  Or what happens when a result overflows. I'm aware 
that this will likely vary depending on whether the arguments are 
arbitrary precision made a runtime or a precision fixed at compile time. 
  In any case, looking through the manual I can't find this information. 
  Of course this package is so ambitious, that it's possible that I've 
missed it but in that case a pointer would be appreciated.

Spending some time on this makes me appreciate what an incredibly 
ambitious accomplishment this is.  It's really unbelievable.  I would be 
curious how frequently various parts of the package are used.
