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. cinderella headshot

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. WebMar 28, 2024 · For two values of the same sign, the two are equivalent, but when the operands are of different signs, the modulo result always has the same sign as the divisor, while the remainder has the same sign as the dividend, which can make them differ by one unit of d. To obtain a modulo in JavaScript, in place of n % d, use ( (n % d) + d) % d.
