所以说,Integer是一个范围内的所有整数,但是范围是就特定计算机而言的(depends on computer). 开始之前,先来了解下很基础的知识 - 计算机的存储单位和整数存储在计算机所占的内存大小。 1).计算机最小的存储单位是“位” 也就是bit或binary digits,用来存放一个二进制数,即 0或1。 8个二进制位为一个字节Byte。
채택된 답변:Walter Roberson MATLAB Online에서 열기 Hello, I am working with the reading in of binary files and I had a question on the fread function. Basically, the datagram format specifies that the data samples are stored as signed 16bit integer (2's compliment). From ...
For example, an 8-bit signed integer has a range of -128 to 127. This means an 8-bit signed integer can store any integer value between -128 and 127 (inclusive) safely. Here’s a table containing the range of signed integers of different sizes: ...
In computer science, an integer is a data type that represents mathematical integers. They may be of different sizes and may or may not be allowed to contain negative values. In a computer they are commonly represented as a group of binary digits.

带符号整数（Signed Integer）是计算机科学中的一个术语，用于表示可以是正数、负数或零的整数。与无符号整数不同，带符号整数有一个额外的位（通常是最高位或最左边的位）来表示正负号，这通常被称为符号位。在计算机中，带符号整数通常以补码的形式存储和运算。补码是一种表示带符号整数的方法，其中正数的补码与其...
char、unsigned char、signed int等，但是integer type不是即分为signed integer type和unsigned integer ...
7 Types bool, char, char16_t, char32_t, wchar_t, and the signed and unsigned integer types are collectively called integral types.48 A synonym for integral type is integer type. The representations of integral types shall define values by use of a pure binary numeration system.49 [ ...
16. 17. 18. 19. 20. Integer C Puzzles int x = foo(); int y = bar(); unsigned ux = x; unsigned uy = y; 1. 2. 3. 4. x<0 infer ((x*2)<0) 不对,可能溢出。 ux>=0 对。 x & 7 == 7 infer (x<<30)<0 对。
1、unsigned的作用就是将数字类型无符号化， 例如 int 型的范围：-2^31 ~ 2^31 - 1，而unsigned int的范围：0 ~ 2^32。看起来unsigned 是个不错的类型，尤其是用在自增或者没有负数的情况。但是在实际使用中会出现一些意外的情况。2、signed在默认情况下声明的整型变量都是有符号的类型（char...
