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。

Scaling of signedintegers in RNS is a problematic and relatively difficult operation which leads to performance bottleneck while implementing signal processing algorithms. But when scaling of an integer is performed by one of its moduli, the complexity of intermodulo operation can be greatly reduced. ...
