## Class template wrapping_int2

boost::date_time::wrapping_int2 — A wrapping integer used to wrap around at the top (WARNING: only instantiate with a signed type).

## Synopsis

    template<typename int_type_, int_type_ wrap_min, int_type_ wrap_max>
    class wrapping_int2 {
    public:
      // types
      typedef int_type_ int_type;

      // construct/copy/destruct
      wrapping_int2(int_type);

      // public member functions
      int_type as_int() const;
      operator int_type() const;
      int_type add(int_type) ;
      int_type subtract(int_type) ;

      // public static functions
      static int_type wrap_value() ;
      static int_type min_value() ;

      // private member functions
      int_type calculate_wrap(int_type) ;
    };

## Description

Bad name, quick impl to fix a bug -- fix later!! This allows the wrap to restart at a value other than 0.

### `wrapping_int2` construct/copy/destruct

1.     wrapping_int2(int_type v);

   If initializing value is out of range of [wrap_min, wrap_max], value will be initialized to closest of min or max

### `wrapping_int2` public member functions

1.     int_type as_int() const;

2.     operator int_type() const;

3.     int_type add(int_type v) ;

   The sign of the returned value will indicate which direction the wraps went. Ex: add a negative number and wrapping under could occur, this would be indicated by a negative return value. If wrapping over took place, a positive value would be returned

4.     int_type subtract(int_type v) ;

   The sign of the returned value will indicate which direction the wraps went. Ex: subtract a negative number and wrapping over could occur, this would be indicated by a positive return value. If wrapping under took place, a negative value would be returned

### `wrapping_int2` public static functions

1.     static int_type wrap_value() ;

2.     static int_type min_value() ;

### `wrapping_int2` private member functions

1.     int_type calculate_wrap(int_type wrap) ;
