问题描述
我一直在考虑编写一个程序来生成世界上最大的素数，这只是为了它的乐趣。这将需要
能够将8000000位数字保存到内存中（25兆位，或者只需一个变量就可以获得超过3兆内存的
...）I也会
需要几个较小的变量。这是因为我越来越优化了一个主要的
数字生成器，直到我想到尝试使用python尝试找到有史以来最大的
。有任何想法吗？我可能会尝试最终在大型机上运行这个
，虽然他们可能不喜欢它很多...我会在家里运行它计算机首先测试它。无论如何，
让我知道是否有办法让python支持数字如此之高。
谢谢！
Python已经支持大数字：
然而，你可能想要看看像gmpy这样的东西，因为你会得到更好的性能。

给定名为Decimal的模块在Python 2.4中，我建议你重命名

I''ve been thinking about writing a program to generate the world''s
largest prime numbers, just for the fun of it. This would require being
able to hold an 8000000 digit number into memory (25 megabits, or a
little over 3 megs of memory for just one variable...) I would also
need several smaller variables. This came about as I optimised a prime
number generator more and more, until I came with the idea to try to
find the largest ever, using python. Any ideas? I''ll probably try to
run this on a mainframe eventually, although they might not like it
very much... I''ll run it on my home computer to first test it. Anyways,
let me know if there''s a way to make python support numbers so high.
Thanks!
Python already supports numbers that large:
However, you probably want to look into something like gmpy, as you''ll
get better performance out of it.

Given the module named "Decimal" in Python 2.4, I''d suggest you to rename
your library.
