• bitwise methods: declare these as private member functions because they are not defined for floating point operations

  double bor(double, double);

  double band(double, double);

  double bxor(double, double);

  double brs(double, double);

  double bls(double, double);

  double bcmpl(double);

• modulus methods: declare these as private member functions because they are not defined for floating point operations

  double mod(double, double);

  double& operator%= (double);

  double& operator% (double);

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

  Double val0(5.0);
  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 generate a random number:

  Double rand_num;
  double value;
  double value1;
         
  // using default seed
  //
  value = rand_num.randSeed();
  
  // generate a random number between min and max
  //
  double min = 0;
  double max = 10.0;
  value1 = rand_num.rand(min, max);
  
  // Gaussian random number generation
  //
  double mean = 5.0;
  double std_dev = 3.0;
  value1 = rand_num.grand(mean, std_dev);
