有英文网站在讨论 HugeCalc
偶查网站的来源分析，发现昨天有英文网站在讨论 HugeCalc：http://forum.projecteuler.net/viewtopic.php?f=12&t=1436#
Hi people,
does anybody of you know C / C++ library HugeCalc?
Its homepage is here: http://www.emath.ac.cn/hugecalc/ (I reccomend putting it in translate.google.com :P )
... and install file is here: http://www.emath.ac.cn/download/HugeCalc_sfx.exe (it installs into Program Files\HugeCalc , but doesn't create any Desktop or Start Menu icon)
I am very impressed by how fast does it compute (and IMHO its simplicity of use, compared to GMP) ... For example, 20 000 000! in under a minute (and you can put it into a file or continue working with it )... Wow! :)
I am currently using it for #231, and ... 20E6 choose 15E6 is done in (guessing) 5-7 seconds. Now I'm prime factorizing it (my own function - slow trial division, HugeCalc doesn't prime factorize), so ... still computing :) 呵呵
有国内人写的可能
当然希望是国外人的 无所谓。
当前我仍主要定位在国内应用，
等比较成熟时才考虑其它语种。 主要是你需要丰富功能
有时候，功能第一，效率第二 可惜有些功能我自己对它的需求都不大，
所以就不太想实现。:L 用数学软件的人
都希望功能多
很少有人喜欢自己扩充 原来是在projecteuler的论坛啊
上星期在做projecteuler的题目，挺好玩的:)
(这星期忙死了:L ) :) 楼主(包括其他各位大侠)的编程水平在国外也也应该算高的.个人觉得.
