下面的程序，有比较简单而且还考虑全面的方法！？？
金额转换：输入 1562 则输出 一千五百六十二元整
输入 1562.456 则输出 一千五百六十二元四角六分
！ ！
我有个想法，先判断输入的字符中有没有“.”，没有的话补上，并补齐后面3位，有“.”不足3位的也补齐3位，然后把“.”前的放一个字符串数组中，后面的放一个字符串数组中，分别转义成汉语数字，前面的分为每4位的处理，后面的 角 分 处理，这样该怎么样实现啊？？？

呵呵,怎么又是这题?

----------------解决方案--------------------------------------------------------
如果能写点汉字,我看起来就不会那么痛苦了
----------------解决方案--------------------------------------------------------
先用正则判断是整数还是浮点数 然后 用取余操作获得 千 百 十 ...的数据 都调用转换汉字方法(自己编写 case 0-9就可以了 取数的时候自然获得 ) 字符串合并 完成读操作
----------------解决方案--------------------------------------------------------
都堆代码了！
