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...

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。
为了[color=red]进行数据类型转化,MySQL提供了CAST()函数[/color],它可以把一个值转化为指定的数据类型。类型有:BINARY,CHAR,DATE,TIME,DATETIME,SIGNED,UNSIGNED 示例: SELECT CAST(NOW() AS SIGNED INTEGER),CURDATE()+0; SELECT 'f'=BINARY 'F','f'=CAST('F' AS BINARY); 九、系统信息函数 DATABASE(...
I currently have functions for signed decimal to binary and signed binary to decimal. The code works fine if you enter a positive integer. However it isn't giving out the correct answers when a negative number is inputted. For example when I input -1 to convert to binary, I will get -...
