Exposes a TypeWrapper for the Python long integer type.
Exposes the numeric
type protocol of Python's built-in long
type. The semantics of the constructors and member functions defined below
can be fully understood by reading the TypeWrapper
concept definition. Since long_
is publicly derived from object
, the public object
interface applies to long_
instances as well.
namespace boost { namespace python { class long_ : public object { public: long_(); // new long_ template <class T> explicit long_(T const& rhs); template <class T, class U> long_(T const& rhs, U const& base); }; }}
namespace python = boost::python; // compute a factorial without overflowing python::long_ fact(long n) { if (n == 0) return python::long_(1); else return n * fact(n - 1); }
