Package rand implements pseudo-random number generators suitable for tasks such as simulation, but it should not be used for security-sensitive work.

ExpFloat64 returns an exponentially distributed float64 in the range (0, +[math.MaxFloat64]] with an exponential distribution whose rate parameter (lambda) is 1 and whose mean is 1/lambda (1) from the default [Source].

Float32 returns, as a float32, a pseudo-random number in the half-open interval [0.0,1.0) from the default [Source].

Float64 returns, as a float64, a pseudo-random number in the half-open interval [0.0,1.0) from the default [Source].

Int returns a non-negative pseudo-random int from the default [Source].

Int31 returns a non-negative pseudo-random 31-bit integer as an int32 from the default [Source].

Int31n returns, as an int32, a non-negative pseudo-random number in the half-open interval [0,n) from the default [Source].

Int63 returns a non-negative pseudo-random 63-bit integer as an int64 from the default [Source].

Int63n returns, as an int64, a non-negative pseudo-random number in the half-open interval [0,n) from the default [Source].

Intn returns, as an int, a non-negative pseudo-random number in the half-open interval [0,n) from the default [Source].

New returns a new [Rand] that uses random values from src to generate other random values.

NewSource returns a new pseudo-random [Source] seeded with the given value.

NewZipf returns a [Zipf] variate generator.

NormFloat64 returns a normally distributed float64 in the range [-[math.MaxFloat64], +[math.MaxFloat64]] with standard normal distribution (mean = 0, stddev = 1) from the default [Source].

Perm returns, as a slice of n ints, a pseudo-random permutation of the integers in the half-open interval [0,n) from the default [Source].

Read generates len(p) random bytes from the default [Source] and writes them into p.

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

Shuffle pseudo-randomizes the order of elements using the default [Source].

Uint32 returns a pseudo-random 32-bit value as a uint32 from the default [Source].

Uint64 returns a pseudo-random 64-bit value as a uint64 from the default [Source].

A Rand is a source of random numbers.

A Zipf generates Zipf distributed variates.

A Source represents a source of uniformly-distributed pseudo-random int64 values in the range [0, 1<<63).

A Source64 is a [Source] that can also generate uniformly-distributed pseudo-random uint64 values in the range [0, 1<<64) directly.
