{{alias}}( [options] )
|
||
|
|
Returns an iterator for generating pseudorandom numbers drawn from a
|
||
|
|
standard normal distribution using the Box-Muller transform.
|
||
|
|
|
||
|
|
If an environment supports Symbol.iterator, the returned iterator is
|
||
|
|
iterable.
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
options: Object (optional)
|
||
|
|
Options.
|
||
|
|
|
||
|
|
options.prng: Function (optional)
|
||
|
|
Pseudorandom number generator (PRNG) for generating uniformly
|
||
|
|
distributed pseudorandom numbers on the interval `[0,1)`. If provided,
|
||
|
|
the `state` and `seed` options are ignored. In order to seed the
|
||
|
|
returned iterator, one must seed the provided `prng` (assuming the
|
||
|
|
provided `prng` is seedable).
|
||
|
|
|
||
|
|
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 iterator has exclusive control over
|
||
|
|
its internal state. Default: true.
|
||
|
|
|
||
|
|
options.iter: integer (optional)
|
||
|
|
Number of iterations.
|
||
|
|
|
||
|
|
Returns
|
||
|
|
-------
|
||
|
|
iterator: Object
|
||
|
|
Iterator.
|
||
|
|
|
||
|
|
iterator.next(): Function
|
||
|
|
Returns an iterator protocol-compliant object containing the next
|
||
|
|
iterated value (if one exists) and a boolean flag indicating whether the
|
||
|
|
iterator is finished.
|
||
|
|
|
||
|
|
iterator.return( [value] ): Function
|
||
|
|
Finishes an iterator and returns a provided value.
|
||
|
|
|
||
|
|
iterator.PRNG: Function
|
||
|
|
Underlying pseudorandom number generator.
|
||
|
|
|
||
|
|
iterator.seed: Uint32Array|null
|
||
|
|
Pseudorandom number generator seed.
|
||
|
|
|
||
|
|
iterator.seedLength: integer|null
|
||
|
|
Length of generator seed.
|
||
|
|
|
||
|
|
iterator.state: Uint32Array|null
|
||
|
|
Generator state.
|
||
|
|
|
||
|
|
iterator.stateLength: integer|null
|
||
|
|
Length of generator state.
|
||
|
|
|
||
|
|
iterator.byteLength: integer|null
|
||
|
|
Size (in bytes) of generator state.
|
