I have uploaded such facets to the vault.
They are called strict_num_put and strict_num_get.

However, they do not throw exceptions, they set the failbit of the 
stream. I noticed that, at least with VC++ 7.1., if the facet throws an 
exception, then the stream catches the exception and sets the failbit 
anyways.
