WebNov 19, 2024 · BTW, Your table needs 0-based indexing because 1 = 2^0\, 2=2^1, 4=2^2, 8=2^3 1 = 20 2 = 21,4 = 22,8 = 23. I.e., 1 is 0th element, 2 is 1st, 4 is 2nd and 8 is 3rd. This way to bitshift by 3 you have to divide (in the case of the right shift) or multiply (in the case of the left shift) by 8. Webn = 0b10111001; n4 = bitand (n,0b1000); n4 = bitshift (n4,-3) n4 = uint8 1. Bit-wise operations can have surprising applications. For example, consider the 8-bit binary representation of the number : 00001000. 8 is a power of 2, so its binary representation contains a single 1. Now consider the number : 00000111.

In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor. Most bitwise operations are presented as two-operand instructions where the result replaces one of the input operands.
