CoCoA:NextPrime

NextPrime

find the next largest prime number

Description

This function computes the smallest prime number greater than N. If

N is negative or too large then the value zero is returned. This

function may generate primes larger than permitted as the characteristic of a finite field in CoCoA. On most platforms primes up to about 45000 can be generated; in some cases a higher limit exists.

Example

  NextPrime(1000);
1009
