PCGRandom (class)

PCG is a family of simple fast space-efficient statistically good algorithms for random number generation. Unlike many general-purpose RNGs, they are also hard to predict.

Signature

export declare class PCGRandom {
  constructor(seedHi?: OptionalNumber, seedLo?: OptionalNumber, incHi?: OptionalNumber, incLo?: OptionalNumber)
}

Added in v2.0.0

getState (method)

Returns a copy of the internal state of this random number generator as a JavaScript Array.

Signature

getState(): PCGRandomState

Added in v2.0.0

setState (method)

Restore state previously retrieved using getState().

Signature

setState(state: PCGRandomState)

Added in v2.0.0

integer (method)

Get a uniformly distributed 32 bit integer between [0, max).

Signature

integer(max: number)

Added in v2.0.0

number (method)

Get a uniformly distributed IEEE-754 double between 0.0 and 1.0, with 53 bits of precision (every bit of the mantissa is randomized).

Signature

number()

Added in v2.0.0

PCGRandomState (type alias)

Signature

export type PCGRandomState = [number, number, number, number]

Added in v2.0.0
