typecasting

I noticed following usage of negate (!) in our code base, like:

int GetIntFromRegistry();

bool bok = !!GetIntFromRegistry();

I am really curious about the usage of !!, it you want to cast the type from int to bool, why not just cast it explicitly use (bool), or static_cast.

Is there anything I am missing?
