Functions

func Float64

func Float64() float64

Float64 returns, as a float64, a pseudo-random number in [0.0,1.0).

func GetSource

func GetSource() interface{}

GetSource returns a copy of the current source of the random number generator.

func Int31n

func Int31n(n int32) int32

Int31n returns, as an int32, a non-negative pseudo-random number in [0,n). It panics if n <= 0.

func Int63

func Int63() int64

Int63 returns a non-negative pseudo-random 63-bit integer as an int64.

func Seed

func Seed(s int64)

Seed uses the provided seed value to initialize the generator to a deterministic state.

func SetSource

func SetSource(newSource interface{})

SetSource sets the source of the random number generator to a copy of the given source.

func String

func String(n int) string

String returns a random string of n characters.
