什么是用于很长很长的常量后缀 [英] What is the suffix used for long long constants

问题描述

如果我想使用类似下面的C code：

If i want to use something like below in a C code:

if(num < 0x100000000LL)

我想的比较发生在一个很长很长不变，但后缀LL不MSVC6.0工作，但它在微软的Visual Studio 2005的工作。

I want the comparison to happen on a long long constant, but suffix LL doesn't work in MSVC6.0 , but it works in MS Visual Studio 2005.

怎样才能得到它在MSVC 6.0的工作？

How can i get it working in MSVC 6.0?

推荐答案

据我所知，长长没有在MSVC 6.0。支持

AFAIK, long long isn't supported in MSVC 6.0.

例如，看看这个的话题。也许，__int64可代替。无论如何，我不知道要使用的其他后缀。

For example, have a look at this discussion thread. Perhaps, __int64 works instead. Anyway, I wouldn't know which other suffix to use.

编辑：__int64似乎工作和配套功能，似乎没有后缀需要在所有。看看这里，例如。还有一些变通方法在本页面的结尾。

__int64 seems to work and for the supporting functions, it seems that no suffix is needed at all. Have a look here, for example. There's also some workaround at the end of this page.
