"WebIn the loop I use to test a number for it's primality it's more efficient to search until sqrt(n) instead of n/2 or even n - 1. But due to rounding problems some number get skipped and thus some primes are skipped! For example, the 10000th prime should be: 104729, but the 'optimized' version ends up with: 103811.

WebA primality test is an algorithm used to determine whether or not a given number is prime. These primality tests come in two di erent varieties; deterministic and probabilistic. Deterministic primality testing algorithms prove conclusively that a number is prime, but they tend to be slow and are not widely used in practice. Web8 Jun 2024 · This is a probabilistic test. Fermat's little theorem (see also Euler's totient function) states, that for a prime number p and a coprime integer a the following equation holds: a p − 1 ≡ 1 mod p. In general this theorem doesn't hold for composite numbers. This can be used to create a primality test. We pick an integer 2 ≤ a ≤ p − 2 ...
