处理大量数字。 [英] Dealing with large numbers.

问题描述

我如何处理C ++中的大数字。示例2 ⁶⁰⁰⁰ 或数字提升到任意两个大素数的幂。



我无法在C ++中处理或存储大数字。有没有办法实现呢？

How can i deal with large numbers in C++. Example 2⁶⁰⁰⁰ or numbers raised to the powers of any two large prime numbers.

I am unable to process or store large numbers in C++. Is there any way to achieve that?

推荐答案

你需要一个大整数库。 Google [ ^ ]是你的朋友。





[更新]

查看以下维基百科页面：

• IEEE浮点数 [ ^ ]。
• 四倍精度浮点格式 [ ^ ]。

You need a library for big integers. Google[^] is your friend.


[update]
Have a look at the following Wikipedia pages:

• "IEEE floating point"[^].
• "Quadruple precision floating-point format"[^].

或许 System.Numerics.BigInteger 正是您要找的：

perhaps System.Numerics.BigInteger is what you are looking for:
