Types

type Source

type Source struct {
	// contains filtered or unexported fields
}

Source is a random source using xorshift64 algorithm.

Marsaglia, George (July 2003). "Xorshift RNGs". Journal of Statistical Software. 8 (14).

Example

package main

import (
	"fmt"
	"math/rand"

	"github.com/shogo82148/randsrc/xorshift64"
)

func main() {
	src := xorshift64.New(1)
	r := rand.New(src)
	for i := 0; i < 10; i++ {
		fmt.Println(r.Int63())
	}
}
