func Float64

func Float64() float64

Float64 returns a random number in [0.0,1.0)

func Intn

func Intn(n int) int

Intn returns a non negative int in [0, n). It will panic if n <= 0.

func Perm

func Perm(n int) []int

Perm returns, as a slice of n ints, a random permutation of the integers [0,n).

func Uint64Bits

func Uint64Bits(n uint) (r uint64)

Uint64Bits generates a random uint64 value in range [0, 2^n). In other words returned uint64 will have n least significant bits set to random values, other bits will be set to 0.

It will panic if there is error reading from crypto/rand source.
