RNG

class guppylang.std.qsystem.random.RNG

Random number generator.

static __new__(seed: int) → RNG

Create a new random number generator using a seed.

discard() → None

Discard the random number generator.

random_advance(delta: int) → None

Advance or backtrack the RNG state by a given number of steps.

Args:

delta: Number of steps to move the RNG state forward (if positive) or backward (if negative).

random_angle() → angle

Generate a random angle in the range \([-\pi, \pi)\).

random_clifford_angle() → angle

Generate a random Clifford angle (multiple of \(\pi/2\)).

random_float() → float

Generate a random floating point value in the range [0,1).

random_int() → int

Generate a random 32-bit signed integer.

random_int_bounded(bound: int) → int

Generate a random 32-bit integer in the range [0, bound).

Args:

bound: The upper bound of the range, needs to less than 2^31.

shuffle(array: array[SHUFFLE_T, SHUFFLE_N]) → None

Randomly shuffle the elements of a possibly linear array in place. Uses the Fisher-Yates algorithm.
