• declare trigonometric methods as private because they cannot be defined for long operations.

   long acos(long); 

   long acosh(long); 

   long asin(long);

   long asinh(long); 

   long atan(long); 

   long atanh(long); 

   long cos(long); 

   long cosh(long); 

   long sin(long);

   long sinh(long); 

   long tan(long); 

   long tanh(long); 

• declare those methods as private which cannot be defined for integer numbers

   long ceil(long);

   long rceil(long);

   long rfloor(long);

   long round(long);

   long floor(long);

   long fraction(long);

• This example shows how to write a Long object into a Sof file:

  Long val0(5);
  String tmp_filename(L"foo");
  Sof tmp_file;
  tmp_file.open(tmp_filename, File::WRITE_ONLY, File::TEXT);
         
  val0.write(tmp_file, (long)0);
  tmp_file.close();
         

• This example shows how to do some mathematic calculations and limit the result to the given range:

  Long value;
  Long value1;
  Long value2;
  
  long coef1 = 7;
  long coef2 = 3;
        
  long min = 0;
  long max = 255;
  
  value1 = 4;
  value2 = 5;
  
  value = value1.exp(2)*coef1 + value2.exp(3)*coef2;
  value.limit(min, max);
