高尔夫代码:数字到单词 [英] Code Golf: Number to Words

问题描述

代码高尔夫系列似乎相当受欢迎.我遇到了一些将数字转换为单词表示形式的代码.一些例子是(2的幂次方为编程带来乐趣):

The code golf series seem to be fairly popular. I ran across some code that converts a number to its word representation. Some examples would be (powers of 2 for programming fun):

• 2->两个
• 1024->一千二十四
• 1048576->一千四百八十五五百七十六

我的同事提出的算法差不多有200行.似乎会有一种更简洁的方法.

The algorithm my co-worker came up was almost two hundred lines long. Seems like there would be a more concise way to do it.

当前准则:

欢迎以任何编程语言提交的内容(我很抱歉 PhiLho最初对此一无所知)
• 最大输入量为2 ^ 64(感谢以下单词，请参见以下链接)
• 短比例尺，英语输出优先，但欢迎使用任何算法.只需连同编程语言一起评论所使用的方法即可.

• Submissions in any programming language welcome (I apologize to PhiLho for the initial lack of clarity on this one)
• Max input of 2^64 (see following link for words, thanks mmeyers)
• Short scale with English output preferred, but any algorithm is welcome. Just comment along with the programming language as to the method used.

推荐答案

Lisp，仅使用标准函数:

Lisp, using only standard functions:

(format nil "~r" 1234) ==> "one thousand two hundred thirty-four"

奖金:

(format nil "~@r" 1234)  ==> "MCCXXXIV"
