As the error message says - the code was trying to convert 
3.3559013980333227e+163 to an integer - and since that won't fit, it threw 
the error.

All of Boost.Math's exception types inherit from std::runtime_error, so a 
catch() for that wouldn't go amiss ;-)

It would also help to know what call resulted in this error - it looks like 
the kind of thing you shouldn't normally see (unless the arguments to some 
function were well out of the range our functions can cope with).

HTH, John.
