leetcode -- 二进制 在学习编程语言的运算符时,大部分语言都会有与,或等二进制运算符,我在初期学习这些运算符的时候,并没有重点留意这些运算符,并且在后续的业务代码中也没有频繁的使用过,直到后来的一些算法题目和源码中经常遇到它们的身影,这些二进制运算符相比普通的运算符具有更快的效率 ...
1个字节它不管怎么样还是只能表示256个数,因为有符号所以我们就把它表示成范围:-128-127。它在计算机中是怎么储存的呢?可以这样理解,用最高位表示符号位,如果是0表示正数,如果是1表示负数,剩下 ...
前提都是8位的整数表示 -128没有原码和反码(只有补码) 那么,为什么规定字长8位时-128没有原码和反码呢?下面解释。 首先看-0,[-0]原码=1000 000,其中1是符号位,求反操作, ...
