   Hi Sean.

   No way to use static_cast<> for this, but lexical_cast<> is ok.

   One thing I do not know about lexical_cast is whether it does any dynamic memory allocation internally which it should not need to do in this specific case. Such memory allocation can throw std::bad_alloc exceptions and may or may not be a performance bottleneck depending on your use-case. If this bothers you, you can always use atoi() or something similar.

   Hope this helps.

   Best regards,
     Jurko Gospodnetiæ
