Faster remainder by direct computation
WebFeb 5, 2024 · On common processors, integer multiplication is many times faster than integer division. Dividing a numerator n by a divisor d is mathematically equivalent to multiplication by the inverse of the divisor (n / d = n x 1/d). If the divisor is known in advance---or if repeated integer divisions will be performed with the same divisor---it can be … WebJun 9, 2014 · I would be very surprised if the loop were more efficient when number is many times larger than mod_number.Any CPU you're likely to use has a built-in division operation that returns both the quotient and the remainder in constant time, and this will be used to implement the % operator. Your loop takes O(number/mod_number) time.. I suggest you …

Indeed, the assumption of Theorem 1 says that c' = c/2^{N+L} is a good approximation of 1/d. Then if n = qd + r, the fractional part of c'n is close to r/d, and multiplying by d reveals r. stamp the contractWeb[Summary]On common processors, integer multiplication is many times faster than integer division.
