### Notlar

Bilginize:

This function uses a probabilistic algorithm to identify primes and chances to get a composite number are extremely small.

``` Negative numbers N always have at least four factors: N*1=N and abs(N)*-1=N. Therefore, even if "natural number" weren't in the definition of a prime (which it is), no negative number would ever qualify. Therefore, the next-largest prime number to any negative number is always 2. ```
``` Prime numbers are positive, non-zero numbers that have exactly two factors. No more, no less. So testing negative numbers doesn't really make any sense. ```
``` It seems gmp_nextprime on negative numbers always returns 2. ```
