如何在Char上执行算术运算 [英] How Do I Perform Arithmetic Operations On Char

问题描述

你好

i需要创建一个处理多个精确数字的类

我需要将这个新类型表示为char，

例如'214587954'

i需要将每个数字转换为添加的ASCII 4位的二进制数

这意味着我需要用4位代表每个数字

并在定义所有可用的运算符后

帮助请我甚至不知道从哪里开始

谢谢

hello
i need to create a class that deals with multiple precision numbers
and i need to represent this new type as char ,
for example '214587954'
i would need to convert each number into binary take of the added ASCII 4 bits
which means that i need to represent each number in 4 bits
and after define all the available operators
help please i don't even know where to start
thank you

推荐答案

请参阅我对该问题的评论。这不是应该如何实施的。传统上，这称为位整数或bitInt。您可以轻松找到合适的实施方案： http://bfy.tw/3PSZ [ ^ ]。



特别是，你可以在这里找到一个实现： https://gmplib.org [ ^ ]。



另一个在这里： http：// sourceforge。 net / projects / ttmath [ ^ ]。

Please see my comments to the question. This is not how such thing should be implemented. Traditionally, this is called "Bit integer" or "bitInt". You can easily find appropriate implementation: http://bfy.tw/3PSZ[^].

In particular, you can find one implementation here: https://gmplib.org[^].

Another one is here: http://sourceforge.net/projects/ttmath[^].
