二进制数字有自己的特殊运算,是对每一位数字分别进行的操作,所以叫做位操作,Python共有以下几种位操作符: x>>y# 返回 x 向右移 y 位得到的结果x<<y# 返回 x 向左移 y 位得到的结果x&y# 且操作,返回结果的每一位是 x 和 y 中对应位做 and 运算的结果,只有 1 and 1 = 1,其他情况位0x|y# 或...
Python 位操作详解：左移操作：定义：将数字的二进制表示向左移动指定的位数。效果：每向左移动一位，相当于乘以2。例如，1 << 2 的结果是4。用途：常用于快速乘以2的幂次。右移操作：定义：将数字的二进制表示向右移动指定的位数。效果：每向右移动一位，相当于除以2。例如，8 >> 2 的结果是2。
|= performs an in-place operation (原地运算符) between pairs of objects. In particular, between: sets: a union operation dicts: an update operation counters: a union (of multisets) operation numbers: a bitwise OR, binary operation In most cases, it is related to the | operator. See examp...
Unlike bitwise AND, OR, and NOT, the bitwise XOR operator (^) doesn’t have a logical counterpart in Python. However, you can simulate it by building on top of the existing operators: Python def xor(a, b): return (a and not b) or (not a and b) It evaluates two mutually excl...
或非操作 (^) 对于x与y的每一位，如果y的位为0，则取x的原始值，如果y的位为1，则取x的对应位求补。例如，对于x=1和y=1，x^y的结果为0。这些位操作在Python中提供了灵活的方式来处理和操纵二进制数据，对于需要高效执行位级操作的场景，如加密、压缩或位图操作等应用特别有用。

In C Programming, the bitwise AND operator is denoted by &. Let us suppose the bitwise AND operation of two integers 12 and 25. 12 = 00001100 (In Binary) 25 = 00011001 (In Binary) Bit Operation of 12 and 25 00001100 & 00011001 ___ 00001000 = 8 (In decimal) Example 1: Bitwise AND...
As a result, the bitwise left-shift operation for 13 (and any other number) can be different depending on the number of bits they are represented by. Because in 32-bit representation, there are many more bits that can be shifted left when compared to 4-bit representation.Previous...

OutRas = BitwiseLeftShift(InRas1, 1) Usage Two inputs are necessary for this bitwise operation to take place. The order of inputs is relevant for this tool. If an input is floating point, the values are converted to integer values through truncation before the bitwise operation is performed...
