Functions

func Coprime

func Coprime(N int) int

Example

package main

import (
	"fmt"

	"github.com/itsubaki/q/math/rand"
)

func main() {
	p := rand.Coprime(15)

	for _, e := range []int{2, 4, 7, 8, 11, 13, 14} {
		if p == e {
			fmt.Println("found")
			break
		}
	}

}

Output:

Example

package main

import (
	"fmt"

	"github.com/itsubaki/q/math/rand"
)

func main() {
	r := rand.CryptoInt64(2, 14)

	for _, e := range []int64{2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13} {
		if r == e {
			fmt.Println("found")
			break
		}
	}

}

Output:
