输出金额成英文

[oscar_zhong]

如题，2,435.20如何转变成TWO THOUSAND FOUR HUNDRED THIRTY FIVE AND CENTS TWENTY
就是在输入金额的时候转换成英文

[一把编程的菜刀]

这个只能提供思路给你，你自己写，懒得写 首先要对一些特殊的做定义，比如0-20,30,40,50,60,70,80,90等等做相应的英文对应成数组 http://wenku.baidu.com/view/21b9f83acaaedd3383c4d39d.html?re=view 具体的怎么对应自己观察上面的网址就知道哪些需要定义了 然后你判断整数部分的长度，就可以到底是属于个，十，百，千，万等中的哪一个范围的了 然后就可以拼出来了，写起了，代码可能会有点长，你自己写吧
