Shifting Pattern
When an integer is shifted right by one bit in a binary system, it is comparable to being divided by two. Since we cannot represent a digit to the right of a binary point in the case of integers since there is no fractional portion, this shifting operation is an integer division.
当一个整数在二进制系统中右移一位时，相当于除以二。由于在整数情况下我们无法表示二进制小数点右侧的数字，因为没有小数部分，因此这种移位操作是整数除法。
- A number is always divided by two when the bit pattern of the number is shifted to the right by one bit.
当数字的位模式右移一位时，数字总是除以二。 - A number is multiplied by two when it is moved left one bit.
当数字向左移动一位时，该数字会乘以 2。
