/**
* Returns a function for generating pseudorandom numbers.
.
*
* ## Notes
*
* - The returned object has the following properties:
*
* - **arity**: number of function parameters.
* - **fcn**: function for generating pseudorandom numbers.
*
* @private
* @param {Collection} x - first parameter
* @param {integer} sx - `x` stride length
* @param {NonNegativeInteger} ox - starting `x` index
* @param {Collection} y - second parameter
* @param {integer} sy - `y` stride length
* @param {NonNegativeInteger} oy - starting `y` index
* @param {boolean} hasOptions - boolean indicating whether to process an options argument
* @param {(void|Options)} options - function options
* @returns {Object} function object
