方法名：getDefaultFractionDigits

Currency.getDefaultFractionDigits介绍

[英]Returns the default number of fraction digits for this currency. For instance, the default number of fraction digits for the US dollar is 2 because there are 100 US cents in a US dollar. For the Japanese Yen, the number is 0 because coins smaller than 1 Yen became invalid in 1953. In the case of pseudo-currencies, such as IMF Special Drawing Rights, -1 is returned.
[中]返回此货币的默认小数位数。例如，美元的默认分数位数为2，因为美元中有100美分。对于日元，这个数字是0，因为小于1日元的硬币在1953年失效。对于伪货币，如IMF特别提款权，返回-1。
