Binary

Usage

var Random = require( '@stdlib/random/array/tools/binary' );

Random( prng, dtypes, dtype )

Constructor for creating arrays filled with pseudorandom values drawn from a binary PRNG.

var arcsine = require( '@stdlib/random/base/arcsine' );

var dtypes = [ 'float64', 'float32', 'generic' ];
var defaultDType = 'float64';

var random = new Random( arcsine, dtypes, defaultDType );

The constructor has the following parameters:

• prng: binary pseudorandom value generator.
• dtypes: list of supported output data types.
• dtype: default output data type.

Random.prototype.generate( len, param1, param2[, options] )

Returns an array filled with pseudorandom values drawn from a binary PRNG.

var arcsine = require( '@stdlib/random/base/arcsine' );

var dtypes = [ 'float64', 'float32', 'generic' ];
var defaultDType = 'float64';

var random = new Random( arcsine, dtypes, defaultDType );

var v = random.generate( 10, 2.0, 5.0 );
// returns <Float64Array>

The method has the following parameters:

• len: output array length.
• param1: first PRNG parameter.
• param2: second PRNG parameter.
• options: function options.

The method accepts the following options:

• dtype: output array data type. Setting this option, overrides the default output array data type.

By default, the method returns an array having the default output array data type. To override the default, set the dtype option.

var arcsine = require( '@stdlib/random/base/arcsine' );

var dtypes = [ 'float64', 'float32', 'generic' ];
var defaultDType = 'float64';

var random = new Random( arcsine, dtypes, defaultDType );

var v = random.generate( 10, 2.0, 5.0, {
    'dtype': 'float32'
});
// returns <Float32Array>

Random.prototype.assign( param1, param2, out )

Fills an array with pseudorandom values drawn from a binary PRNG.

var arcsine = require( '@stdlib/random/base/arcsine' );
var zeros = require( '@stdlib/array/zeros' );

var dtypes = [ 'float64', 'float32', 'generic' ];
var defaultDType = 'float64';

var random = new Random( arcsine, dtypes, defaultDType );

var out = zeros( 10, 'float64' );
// returns <Float64Array>

var v = random.assign( 2.0, 5.0, out );
// returns <Float64Array>

var bool = ( v === out );
// returns true

The method has the following parameters:

• param1: first PRNG parameter.
• param2: second PRNG parameter.
• out: output array.
