4.3版
Current version : PiFast43 (version 4.3, released on Jul 05 2003, fixed on Jul 08 2003).
New features of version 4.3 :
* Faster than previous version : 4-5% for pi computations, and more (10-15%) for
e computations
* A serious (but rare) bug discovered by Shigeru Kondo in the computation of
64 million digits of e=1/exp(-1) was fixed. The bug existed since version 4.0
* Ability to specify a factor suffix k,K,m,M,g,G after the number of digits
(k=1000,K=1024,m=1000000,M=1,048,576...)
* Maximum number of digits is now 17 billion (instead of 12 billion with previous versions)

一年前就玩過這個了,當時還拿quickpi來比較
quickpi在數值不大的時候比pifast還快很多
(而且記憶體使用量極大)
不過最新版pifast好像比quickpi快了 |
