有无限整数吗？ [英] Is there an infinite integer?

问题描述

我目前正在开发一种游戏，我的位置可以在整数中变化。例如：

I am currenty developing a game where my position can change in an integer. For instance:

Player.X -= Player.WalkingSpeed;

现在我假设整数是无限的，但为了确保，我做了一个快速的谷歌检查，发现这个：



< a href =http://msdn.microsoft.com/en-us/library/5kzh1b5w%28v=vs.80%29.aspx> http://msdn.microsoft.com/en-us/library/5kzh1b5w ％28v = vs.80％29.aspx [ ^ ]



这告诉我一个整数范围从-2,147,483,648到2,147,483,647。有什么方法可以制作一个（我的）整数（所以它）不停在-2,147,483,648和2,147,483,647？



编辑：欢迎任何其他解决方案，但我需要它是一个整数，因为我不能使用双打。

Now I presumed that the Integer was infinite, but to make sure, I did a quick google check and found this:

http://msdn.microsoft.com/en-us/library/5kzh1b5w%28v=vs.80%29.aspx[^]

Which is telling me that an integer ranges from -2,147,483,648 to 2,147,483,647. Is there any way I can make an(my) integer (so it)that does not stop at -2,147,483,648 and 2,147,483,647?

Any other solutions are welcome to, but I need it to be a whole number since I can not use doubles.

推荐答案

没有。而且不需要它。但你可以使用正负无穷大而不是浮点类型的数字，并用这些值进行值算术。







请参阅： http://en.wikipedia.org/wiki/IEEE_754 [ ^ ]。

No. And it is not needed. But you can use positive and negative infinity and not-a-number with floating-point types and do value arithmetic with those values.

没有无限整数，但可以使用Long。其区间为负9,223,372,036,854,775,808，为正9,223,372,036,854,775,807。这是正负九元素。

There is not an infinite integer, but you can use a Long. Its range is negative 9,223,372,036,854,775,808 to positive 9,223,372,036,854,775,807. That is plus or minus nine quintillion.
