Class LinearCongruentialGenerator

constructor

• new LinearCongruentialGenerator(): LinearCongruentialGenerator

  Set modulus, multiplier, and increment. Initialize rand_state according to Date.now().

  Returns LinearCongruentialGenerator

Readonlyincrement

Readonlymodulus

Readonlymultiplier

getState

• getState(): number

  Get the current generator state for deterministic restoration.

  Returns number

nextInt

• nextInt(): number

  Generate the next integer in the range (0, this.modulus) non-inclusive, updating rand_state.

  Postcondition: pass checkRandState(), i.e. rand_state > 0 and is an integer.

  Returns number

randomFloat

• randomFloat(): number

  Generates random float between (0, 1) non-inclusive, updating rand_state.

  Postcondition: pass checkRandState(), i.e. rand_state > 0 and is an integer.

  Returns number

setSeed

• setSeed(seed: number): void

  Sets rand_state after normalized with modulus to ensure that it is within range.

  Parameters

  • seed: number

    Any integer. Used to set rand_state after normalized with modulus.

    Postcondition: pass checkRandState(), i.e. rand_state > 0 and is an integer.

  Returns void

setState

• setState(state: number): void

  Restore a state returned by getState().

  Parameters

  • state: number

  Returns void
