Functions

seed(seed int): uses the provided seed value to initialize the default Source to a deterministic state.
exp_float() => float: 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.
float() => float: returns, as a float64, a pseudo-random number in [0.0,1.0) from the default Source.
int() => int: returns a non-negative pseudo-random 63-bit integer as an int64 from the default Source.
intn(n int) => int: returns, as an int64, a non-negative pseudo-random number in [0,n) from the default Source. It panics if n <= 0.
norm_float) => float: 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(n int) => [int]: returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n) from the default Source.
read(p bytes) => int/error: generates len(p) random bytes from the default Source and writes them into p. It always returns len(p) and a nil error.
rand(src_seed int) => Rand: returns a new Rand that uses random values from src to generate other random values.

seed(seed int): uses the provided seed value to initialize the default Source to a deterministic state.
exp_float() => float: 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.
float() => float: returns, as a float64, a pseudo-random number in [0.0,1.0) from the default Source.
int() => int: returns a non-negative pseudo-random 63-bit integer as an int64 from the default Source.
intn(n int) => int: returns, as an int64, a non-negative pseudo-random number in [0,n) from the default Source. It panics if n <= 0.
norm_float) => float: 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(n int) => [int]: returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n) from the default Source.
read(p bytes) => int/error: generates len(p) random bytes from the default Source and writes them into p. It always returns len(p) and a nil error.
