如何负数再$ P $ 32位有符号整数psented?
它是二的或者一个补?或左侧的最后一个比特是像一个标志?
例如:(-10)
How are negative number represented in 32-bit signed integer?Is it two's or one's complement? or the last bit on the left is like a flag?For example: (-10)
推荐答案
大多数计算机,这些天使用对于有符号整数,但它可以通过硬件结构,程序设计语言,或者其他特定于平台的问题而变化。
Most computers these days use two's complement for signed integers, but it can vary by hardware architecture, programming language, or other platform-specific issues.
有关一个二进制补码重新presentation,最左边的比特被称为符号位的,它会被用于负整数设置和清除为一个非负整数。然而,它不仅仅是一个标记的更多。请参阅更多信息。
For a two's-complement representation, the leftmost bit is referred to as the sign bit, and it will be set for a negative integer and clear for a non-negative integer. However, it is more than just a "flag". See the Wikipedia article for more information.
