WebModulo in C++ can be done using % operator, but just as division, it is quite slow. So when doing a common operation of cycling between subsequent numbers from a limited range: x2 = (x1 + 1) % n; few alternatives have been developed for some special cases, using bitwise operations. First, when the divisor is a power of 2, we can use bitwise and ... Web2 days ago · Compute n modulo d without division(/) and modulo(%) operators, where d is a power of 2 number.

WebI've heard you can use the logical AND to turn moduli of the form (2^n) into bitwise functions of the form ((2^n)-1). I.E. You could AND the ARRAY_SIZE with '7' (if doing 8 unrolls) and get the remainder. I tried simply doing: efficientRemainder = ARRAY_SIZE && 7 (and similar), but this is quite wrong. Or the source is incorrect. WebThen, the corresponding binary logic operators are applied bitwise; that is, each bit of the result is set or cleared according to the logic operation (NOT, AND, OR, or XOR), applied …

WebAug 2, 2024 · For modulo operations, the only difference is that the % symbol is used in C#. + The addition operator is the same in X++ and C#. The plus sign is also used for string concatenation.

You are confusing operations on a single bit with operations on a byte,or word. (Multiple bits) A single bit represents either 0 or 1 depending on its value. If you add two bits, and ignore the carry, you are adding "mod2". 0+0 = 0 0+1 = 1 1+0 = 1 1+1 overflows, or carries, and you have 0. this is exactly the same as XOR.
