Functions

func Boolean

func Boolean() bool

Boolean returns true or false with equal probability.

func Geometric

func Geometric() float64

Geometric returns a float64 that counts the number of Bernoulli trials until the first success for a success probability of 0.5.

func I63n

func I63n(n int64) int64

I63n returns an integer from the set {0,...,n-1} uniformly at random. The value of n must be positive.

func Normal

func Normal() float64

Normal returns a normally distributed float with mean 0 and standard deviation 1.

func Sign

func Sign() float64

Sign returns +1.0 or -1.0 with equal probabilities.

func U64

func U64() uint64

U64 returns a uniformly random uint64.

func U8

func U8() uint8

U8 returns a uniformly random uint8.

func Uniform

func Uniform() float64

Uniform returns a float64 from the interval (0,1] such that each float in the interval is returned with positive probability and the resulting distribution simulates a continuous uniform distribution on (0, 1].
