存储并打印整数值大于2 ^ 64 [英] Storing and printing integer values greater than 2^64

问题描述

我想写寻找梅森素数的程序。使用无符号long long类型，我能够确定9梅森素数，这是（2 ^ 61）-1的值。为较大的值，我需要，可以存储整数值大于2 ^ 64更大的数据类型。请帮忙。 （我应该能够使用类似的，运营商的=，>，＆LT;和％这种数据类型）

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. Please help. (I should be able to use operators like ,=,>,< and % with this data type.)

推荐答案

您不能做你想做的用C当地人的类型，但也有一些让处理任意大的数字，喜欢的the GNU多个precision运算库。

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.
