NOR Calculator

Our NOR Calculator applies the bitwise NOR operation to two numbers, bit by bit. Enter each number as decimal, binary, or octal, choose a bit width, and get the result in every format at once.

NOR Operation Explained

NOR: a result bit is 1 only when both numbers have a 0 in that position; if either number has a 1 in that position, the result bit is 0. NOR is the negation of OR — formula: A NOR B = NOT (A OR B).

Truth Table

A  B  |  NOR
0  0  |   1
0  1  |   0
1  0  |   0
1  1  |   0

Example Calculation (8-bit)

A = 12 (00001100), B = 10 (00001010)

OR: 00001100 | 00001010 = 00001110

NOR: NOT(00001110) = 11110001 = 241
