For java: BigDecimal b1 = new BigDecimal("9999999999999999.0");

        BigDecimal b2 = new BigDecimal("9999999999999998.0");


        System.out.println(b1.subtract(b2));

prints 1.0

Python:

    >>> import decimal
    >>> decimal.Decimal('9999999999999999.0')-decimal.Decimal('9999999999999998.0')
    Decimal('1.0')
