存储和打印大于 2^64 的整数值 [英] Storing and printing integer values greater than 2^64

问题描述

我正在尝试编写一个程序来查找梅森素数.使用 unsigned long long 类型，我能够确定第 9 个梅森素数的值，即 (2^61)-1.对于更大的值，我需要一种可以存储大于 2^64 的整数值的数据类型.

I am trying to write a program for finding Mersenne prime numbers. Using the unsigned long long type I was able to determine the value of the 9th Mersenne prime, which is (2^61)-1. For larger values I would need a data type that could store integer values greater than 2^64.

我应该能够使用像 *、*=、>、< 和% 使用此数据类型.

I should be able to use operators like *, *=, > ,< and % with this data type.

推荐答案

你不能用 C 原生类型做你想做的事，但是有一些库可以处理任意大的数字，比如 GNU 多精度算术库.

You can not do what you want with C natives types, however there are libraries that let handle arbitrarily large numbers, like the GNU Multiple Precision Arithmetic Library.
