   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.
