// Create via a string
    BigDecimal bd1 = new BigDecimal("123456789.0123456890");
    
    // Create via a long
    BigDecimal bd2 = BigDecimal.valueOf(123L);
    
    bd1 = bd1.add(bd2);
    bd1 = bd1.multiply(bd2);
    bd1 = bd1.subtract(bd2);
    bd1 = bd1.divide(bd2, BigDecimal.ROUND_UP);
    bd1 = bd1.negate();
