This package provides functions for computing prime numbers in Julia.


The package is available for Julia versions 0.4 and up. To install it, run


from the Julia REPL.


Prior to Julia 0.5, these (or similar) functions were available in Julia's Base module. Because of this, the symbols from this package are not exported on Julia 0.4 to avoid naming conflicts. In this case, the symbols will need to be explicitly imported or called with the prefix Primes. For example,

using Primes
import Primes: isprime, primes, primesmask, factor

This is not necessary for Julia versions 0.5 or later.
