Introduction

+ +

Exposes a TypeWrapper for the Python + long + integer type.

+ +

Classes

+ +

Class long_

+ +

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.

+ +

Class long_ + synopsis

+
+namespace boost
+{
+  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);
+  };
+}
+
+ +

Example

+
+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);
+}
