//  Additive Pattern for numeric classes
//  ------------------------------------

//  Instructions:

//  1.  Paste the code below into the class being defined.
//  2.  Substitute the class name for "Class"
//  3.  Substitute the name of any interacting pure number type
//      for "PURE_TYPE
//  4.  Fill in the bodies of the incomplete functions below.


public: Class  addSet(Class     rs) {                    return this;}
public: Class  addSet(PURE_TYPE rs) {                    return this;}
public: Class  subSet(Class     rs) {                    return this;}
public: Class  subSet(PURE_TYPE rs) {                    return this;}
public: Class  mpySet(PURE_TYPE rs) {                    return this;}
public: Class  divSet(PURE_TYPE rs) {                    return this;}
public: Class  modSet(Class     rs) {                    return this;}
public: Class  modSet(PURE_TYPE rs) {                    return this;}
public: PURE_TYPE div(Class  rs)    {return                         ;}

public: Class  minus()              {return                         ;}


//  Completely defined functions -- no fill-in needed:
//  ----------------------------

public: Class  add(Class     rs) {return new Class(this).addSet(rs);}
public: Class  sub(Class     rs) {return new Class(this).subSet(rs);}
public: Class  mpy(PURE_TYPE rs) {return new Class(this).mpySet(rs);}
public: Class  div(PURE_TYPE rs) {return new Class(this).divSet(rs);}
public: Class  mod(Class     rs) {return new Class(this).modSet(rs);}
public: Class  mod(PURE_TYPE rs) {return new Class(this).modSet(rs);}
