Handy for learning bitwise logic, setting permission or flag bits and digital-logic exercises. Processed locally.
二进制 NOR 运算（或非）NOR Binary Values
把两个或多个二进制数按位做 NOR（或非）运算：先按位 OR，再全部取反，只有所有数在该位都是 0 时结果才是 1。可以每行一组分别计算或所有数一起计算，位数不同时右端对齐左边补 0，可设置最少位数、显示竖式和十进制结果。适合学习逻辑门（NOR 是通用门）、数字电路和位运算练习，数据在本地处理。Apply bitwise NOR to two or more binary values: OR them and invert the result, so a bit is 1 only where every value has a 0.

Handy for learning logic gates (NOR is a universal gate), digital electronics and bitwise exercises. Processed locally.

Work each line separately or combine all values; different lengths are right-aligned with leading zeros. Set a minimum width, show the working and see the result in decimal. Handy for learning logic gates (NAND is a universal gate), digital electronics and bitwise exercises. Processed locally.
二进制 NOT 运算（按位取反）NOT Binary Values
把每个二进制数按位取反（NOT，反码）：0 变 1，1 变 0。每行可以有多个数，结果保持原来的排列；可设置最少位数（例如按 8 位取反），保留或去掉前导 0，并同时显示十进制结果。适合学习位运算、计算反码和补码、做数字电路练习，数据在本地处理。Invert every bit of each binary value (bitwise NOT, ones' complement): 0 becomes 1 and 1 becomes 0. A line can hold several values and the layout is kept. Set a minimum width (e.g. invert as 8 bits), keep or drop leading zeros, and see the decimal value too. Handy for learning bitwise logic, working out ones' and two's complement and digital-logic exercises. Processed locally.
二进制循环移位（位旋转 ROL / ROR）Rotate Binary Bits

Rotating left (ROL) moves the bits that fall off the left back in on the right; rotating right (ROR) moves the bits from the right back to the left, so the number of 1s never changes. Set how many positions to rotate and the bit width (each value's own length by default, or a fixed 8, 16 or 32 bits with leading zeros), process many values at once and show decimal results. Handy for learning bit operations, hash and cipher algorithms (SHA, rotating shift registers) and assembly exercises. Processed locally.

Let the result grow so no bits are lost, or keep the original length or a fixed width (8, 16 or 32 bits), in which case the bits pushed out on the left are dropped and the tool tells you which were lost and whether it overflowed. Process many values at once and show decimal results. Handy for learning bit operations, multiplying by powers of two and assembly exercises. Processed locally.
二进制右移（逻辑右移 >>> / 算术右移 >>）Shift Binary Right

A logical shift (>>>) brings in zeros on the left; an arithmetic shift (>>) copies the sign bit (the top bit), which suits signed two's-complement numbers. The length is kept by default, or the shifted-out bits can simply be removed so the result gets shorter, and the tool tells you which 1s fell off the right (the discarded remainder). Each position divides by 2 rounding down. Process many values at once and show decimal results. Processed locally.
二进制位随机打乱（洗牌，保持 1 的个数）Shuffle Binary Bits
把每个二进制数的各个位随机打乱顺序：位数和 1 的个数保持不变，只是位置被重新排列。可以填写种子让结果可复现，也可以让所有数使用同一种打乱方式（同一个置换），并显示每一位移到了哪里，方便按同样的置换还原。适合生成测试数据、出题、学习置换和简单的位混淆，数据在本地处理。Shuffle the bits of each binary number into a random order. The length and the number of 1s stay the same; only the positions change. Enter a seed for a reproducible result, use the same shuffle (one permutation) for every value, and show where each bit moved so the same permutation can be undone. Handy for test data, exercises, learning about permutations and simple bit scrambling. Processed locally.
二进制 XOR 运算（按位异或）XOR Binary Values
把两个或多个二进制数按位做 XOR（异或）运算：两个数在该位不同时结果为 1，相同时为 0；多个数时，该位上 1 的个数为奇数结果就是 1（奇偶校验）。可以每行一组分别计算，也可以把所有数一起计算；位数不同时右端对齐左边补 0，可显示竖式、十进制和十六进制结果。适合学习位运算、校验和、简单加密（异或密钥）和数字电路练习，数据在本地处理。Apply bitwise XOR to two or more binary values: a result bit is 1 where two values differ and 0 where they match; with more values it is 1 where an odd number of them have a 1 (parity). Work each line separately or combine all values; different lengths are right-aligned with leading zeros. Show the working and the result in decimal and hex too. Handy for learning bitwise logic, checksums, simple XOR ciphers and digital-logic exercises. Processed locally.
