you should first test number precision first, choose right number precision. how to choose right number type ? maybe the following works:

BigDecimal  number = new BigDecimal("0.0");
                String value = number.toString();
                if(value.equals(Double.toString(number.doubleValue()))){
                     //use double type, which is enouch
                }else {
                    //bigdecimal
                }
