大小以千字节为单位？ [英] size in kbytes?
问题描述
我分配一些size_t的内存，但想表达：
printf（"分配的内存总量是：％lu bytes.\ n，（unsigned
long）total_mem）;
，以千字节为单位。方法1或2是正确的吗？我已经看过两个
解释使用谷歌：
1）
printf（"分配的内存总量是：％lu kb.\ n"，（unsigned long）
total_mem / 1024）;
2）
printf （分配的内存总量为：％lu kb.\ n，（unsigned long）
total_mem / 1000）;
祝你好运/ Med venlig hilsen

在数据存储上下文中，前缀K通常等于1024，而在网络
传输上下文中它可能是等于1000.前缀Ki设置为1024，因此1 KiB =
1024字节。

什么你会用，为什么？什么是正常的？
我认为1024更正确...？

Hi,
I allocate some memory of size_t but want to express:
printf("Total amount of allocated memory is: %lu bytes.\n", (unsigned
long) total_mem);
in kilo-bytes. So is method 1 or 2, the correct one? I''ve seen both
explanations using google:
1)
printf("Total amount of allocated memory is: %lu kb.\n", (unsigned long)
total_mem/1024);
2)
printf("Total amount of allocated memory is: %lu kb.\n", (unsigned long)
total_mem/1000);
Best regards / Med venlig hilsen

Depends on your definition of kilobyte

In data storage context the prefix K usually equals 1024, while in network
transfer context it may equal 1000. The prefix Ki is set to 1024, so 1 KiB =
1024 bytes.

What would you use and why? What''s "normal" ?
I think 1024 is more correct...?
