The numbers vary by architecture, and have a wide range even for Haswell specifically, but an 8x loss in performance seems reasonable.

Nettet1. feb. 2010 · Well, most programming languages have a built-in operator for this. For example, in C-derived languages, the % operator is the modulus operator. Thus, int p = 625 % 221 would assign 183 to p.You can achieve the same functionality by dividing 625 by 221 as integer division and getting the answer 2.Then you take 625 - 2 * 221 to get … Nettet12. feb. 2024 · That is approximately the same performance ratio between the Java code and the C#-with-builtin-BigInteger code as you observed: multiply a little faster in Java, modPow more than 10x faster in Java.

The problem that we are trying to solve is, given a composite number, to find a non-trivial divisor of (a divisor strictly between and ).Before attempting to find such a divisor, if there's any doubt whether is composite or prime, one can use relatively quick primality-testing algorithms to verify that is indeed composite, although this is not a part …

Note however that if n has a known non zero value at compile time, matrix [i] % n would be compiled as a multiplication with a small adjustment, which should be much faster than both the integer modulus and the floating point modulus.

Nettet34 I read somewhere once that the modulus operator is inefficient on small embedded devices like 8 bit micro-controllers that do not have integer division instruction. Perhaps someone can confirm this but I thought the difference is 5-10 time slower than with an integer division operation.
