http://www.mypiday.com/ 没有程序, 只有应用, 用来算自己的Pi day  http://www.piday.org/million/ pi 一百万位, 够不够? http://www.angio.net/pi/digits.html 有连接可以找到 pi的前 5万亿位, 应该够你用的吧. Need more than a million digits? Here are some places to look: •4 million digits (compressed): zenwerk.com •50 million digits (compressed, special): You can download 50 million from the Pi searcher here. These digits are packed together two per byte, so you'll have to download, compile, and use this program to print them. Geeks only, sorry. •4 billion digits: Available in various formats from pi.super-computing.org. •5 trillion digits (requires special viewer): Alexander Yee makes 5 trillion digits available via bittorrent. He also has a lot of other large numbers. (He holds the record for most digits of Pi computed.) Alternately, you could download a program to compute pi and compute them yourself. Alexander Yee's y-cruncher for Windows and Linux is the fastest program out there. On a fast computer, it can compute 1 billion digits in perhaps 10 minutes. If you prefer the open source route, check out how to compute Pi using GMP, one of the most popular open-source math libraries. |
