Features

Operators

• Assignment: =

  Right-hand-side operand can be BigDecimalInt, int up to long long or string

  BigDecimalInt num1, num2;
  num1 = 1234567890;
  num1 = "123456789012345678901234567890";
  num1 = num2;
  

• Binary arithmetic: +, -

  BigDecimalInt num1, num2;
  num1 = num2 + num2;
  num1 = num2 - "123456789012345678901234567890";
  num1 = num1 - 1231345;
  

• Arithmetic-assignment: +=, -=

  BigDecimalInt num1, num2;
  num1 += num2;
  num1 -= 1234567890;
  num1 -= "1234567890";
  

• Increment & Decrement : ++, --

• BigDecimalInt num1, num2;
  num1 = ++num2;   // pre-increment
  num1 = --num2;   // pre-decrement
  num1 = num2++;   // post-increment
  num1 = num2--;   // post-decrement
  

• Comparison: <, >, ==, !=, <=,>=

  BigDecimalInt num1, num2;
  if ( num1 > num2
      || num1 < num2
      || num1 <= num3
      || num1 >= num2
      || num1 == num3
      || num1 != num3
      ...            ) {
      
  }

• I/O stream: <<, >>

  BigDecimalInt num1, num2;
  cin >> num1 >> num1;
  cout << num1 << ", " << num1 << '\n';
