{{alias}}()
Returns a pseudorandom integer on the interval `[1, 4294967295]`.
This pseudorandom number generator (PRNG) is a 32-bit Mersenne Twister
pseudorandom number generator.
The PRNG is *not* a cryptographically secure PRNG.
The PRNG has a period of 2^19937 - 1.
Returns
-------
r: integer
Pseudorandom number.
Examples
--------
> var r = {{alias}}();
{{alias}}.normalized()
Returns a pseudorandom number on the interval `[0,1)` with 53-bit precision.
Returns
-------
r: number
Pseudorandom number.
Examples
--------
> var r = {{alias}}.normalized();
{{alias}}.factory( [options] )
Returns a 32-bit Mersenne Twister pseudorandom number generator.
Parameters
----------
options: Object (optional)
Options.
options.seed: integer|ArrayLikeObject<integer> (optional)
Pseudorandom number generator seed. The seed may be either a positive
unsigned 32-bit integer or, for arbitrary length seeds, an array-like
object containing unsigned 32-bit integers.
options.state: Uint32Array (optional)
Pseudorandom number generator state. If provided, the `seed` option is
ignored.
options.copy: boolean (optional)
Boolean indicating whether to copy a provided pseudorandom number
generator state. Setting this option to `false` allows sharing state
between two or more pseudorandom number generators. Setting this option
to `true` ensures that a returned generator has exclusive control over
its internal state. Default: true.
Returns
-------
rand: Function
Pseudorandom number generator (PRNG).
Examples
--------
// Basic usage:
> var rand = {{alias}}.factory();
> r = rand();
> r = rand();
// Provide a seed:
> rand = {{alias}}.factory( { 'seed': 1234 } );
> r = rand()
822569775
{{alias}}.NAME
Generator name.
Examples
--------
> var str = {{alias}}.NAME
'mt19937'
{{alias}}.MIN
Minimum possible value.
Examples
--------
> var v = {{alias}}.MIN
1
{{alias}}.MAX
Maximum possible value.
Examples
--------
> var v = {{alias}}.MAX
4294967295
{{alias}}.seed
Pseudorandom number generator seed.
Examples
--------
> var seed = {{alias}}.seed;
{{alias}}.seedLength
Length of generator seed.
Examples
--------
> var len = {{alias}}.seedLength;
{{alias}}.state
Generator state.
Examples
--------
> var r = {{alias}}()
<number>
> r = {{alias}}()
<number>
> r = {{alias}}()
<number>
// Get a copy of the current state:
> var state = {{alias}}.state
<Uint32Array>
> r = {{alias}}()
<number>
> r = {{alias}}()
<number>
// Set the state:
> {{alias}}.state = state;
// Replay the last two pseudorandom numbers:
> r = {{alias}}()
<number>
> r = {{alias}}()
<number>
{{alias}}.stateLength
Length of generator state.
Examples
--------
> var len = {{alias}}.stateLength;
{{alias}}.byteLength
Size (in bytes) of generator state.
Examples
--------
> var sz = {{alias}}.byteLength;
{{alias}}.toJSON()
Serializes the pseudorandom number generator as a JSON object.
Returns
-------
out: Object
JSON representation.
Examples
--------
> var o = {{alias}}.toJSON()
{ 'type': 'PRNG', 'name': '...', 'state': {...}, 'params': [] }
