大的数字与分数支持 [英] Big numbers with fraction support

问题描述

我需要一个C＃号的东西，可以处理非常大的数字，但也部分支持，我看着System.Numberics.BigInteger即将在.NET 4.0中，但我不能让它与部分工作。

 东西我= 2; 
的东西J = 5; 
的东西K = 1 / J; //应为0.4 
  

当我试图

 的BigInteger我= 2; 
 BigInteger的J = 5; 
双D =（双）（I / J，）; // d为0.0 
  

有谁知道这样的图书馆吗？

< DIV CLASS =h2_lin>解决方案

我曾经用这个库：
W3B .Sine 。它是：

在C＃开发的一个任意精度的十进制数
库

您也可以尝试 HTTP：// WWW .fractal-landscapes.co.uk / bigint.html 。不过，我使用它没有经验。

I need a c# number something that can handle very large numbers but also fraction support, I looked at System.Numberics.BigInteger coming in .NET 4.0 but I can't get it to work with fractions.

something i = 2;
something j = 5;
something k = i/j; //should be 0.4

when i tried

 BigInteger i = 2;
 BigInteger j = 5;
 double d = (double)(i/j); //d is 0.0

Does anybody know such a library?

解决方案

I once used this library: W3b.Sine. It's:

An arbitrary-precision decimal number library developed in C#.

You could also try http://www.fractal-landscapes.co.uk/bigint.html. However, I have no experience using it.
