Re: [Boost-users] [numeric conversation] behavior on std::numeric_limits<double>::max() + eps with numeric_cast

I would expect that an exception is thrown which isn't, the output is 1.79769e+308 1.79769e+308

In the case of conversion to the same type I believe a trivial fall through is done which just returns the value, so this is the expected behavior.

and as second: If I write my onw UDT as shown in the tutorial like:

it doesn't change the result - is this the right way?

It's hard for me to tell just from the code snippets you've provided. Could you send me a small test which shows the problem you're having? Thanks, Brandon Kohn
