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.

I would like to know whether there are any formulas related to bitwise xor operation (16 ^ 3 = 19, 5 ^ 7 = 2). I thought that there might exist anything like: (A ^ B) % P = (A % P ^ B % P) % P. which is clearly not the case.

WebModulo operations might be implemented such that a division with a remainder is calculated each time. For special cases, on some hardware, faster alternatives exist. For example, the modulo of powers of 2 can alternatively be expressed as a bitwise AND operation (assuming x is a positive integer, or using a non-truncating definition): 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#.
