Functions ¶
func Float32 ¶ added in v0.2.3
func Float32() float32
Float32 returns, as a float32, a pseudo-random number in [0.0,1.0).
func Float64 ¶
func Float64() float64
Float64 returns, as a float64, a pseudo-random number in [0.0,1.0).
func Int31 ¶
func Int31() int32
Int31 returns a non-negative pseudo-random 31-bit integer as an int32.
func Int31n ¶ added in v0.2.3
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 Int63n ¶ added in v0.2.3
Int63n returns, as an int64, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
func Intn ¶ added in v0.2.3
Intn returns, as an int, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
func Perm ¶ added in v0.2.3
Perm returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n).
